    There was described a condition for the action of hydrogen peroxide on some mercapto-pyrimidines. 2-Ethylmercapto-pyrimidines [Ⅰ, X=Cl, OCH_3, OC_2H_5, NH_2, NHCH_3 or N(C_2H_5)_2] reacted with hydrogen peroxide in ethanol to form 2-hydroxy-pyrimidines [Ⅱ, X=Cl, OCH_3, OC_2H_5, NH_2, NHCH_3 or N(C_2H_5)_2]. The reaction is represented as follows: In case that X in formula Ⅰ was C_2H_5S, it was possible to prepare uracil (Ⅱ, X=OH).By means of the above mentioned new reaction, the following pyrimidine derivatives...

The reaction is represented as follows: In case that X in formula Ⅰ was C_2H_5S, it was possible to prepare uracil (Ⅱ, X=OH).By means of the above mentioned new reaction, the following pyrimidine derivatives were prepared:2-Hydroxy-4-X-pyrimidine (Compound Ⅱ)Nature of X Empirical Formula m.p.CI C_4H_3ON_2Cl 152-154°OCH_3 C_5H_6O_2N_2 132-134°OC_2H_5 C_6H_8O_2N_2 168-170°OH C_4H_4O_2N_2 320°(with becomposition)NH_2 C_4H_5ON_3 290-292°(with decomposition; needles transformed to cubes at 190°)X=NHCH_3 C_5H_7ON_3 268°X=N(C_2H_5)_2 C_8H_(13)ON_3 280-281°The mechanism of the action of hydrogen peroxide on 2-ethylmercapto-4-chloro-pyrimidine was considered as follows: 2-Ethylmercapto-4-chloro-pyrimidine reacted with hydrogen peroxide to form 2-ethylsulphonyl-4-chloro-pyrimidine, which was then further oxidized by hydrogen peroxide to yield 2-hydroxy-4-chloro-pyrimidine and ethyl sulphonic acid. For supporting this interpretation, the authors attempted to oxidize with hydrogen peroxide 2-ethylsulphonyl-4-chloropyrimidine, which was prepared by Sprague and Johnson's method.2-Ethylmercapto-6-alkoxy-pyrimidine (Ⅰ, X=OCH_3 or OC_2H_5) reacted with hydrogen peroxide in ethanol to form 2-hydroxy-4-alkoxy-pyrimidine (Ⅱ, X=OCH_3 or OC_2H_5) in a lower yield and uracil in a higher yield. This phenomenon was interpreted as follows: 2-ethylmercapto-6-alkoxy-pyrimidine (Ⅰ, X= OCH_3 or OC_2H_5) reacted with hydrogen peroxide to form 2-hydroxy-4-alkoxy-pyrimidine (Ⅱ, X=OCH_3 or OC_2H_5) and ethyl sulphonic acid, the latter acting as a catalyst, which would accelerate the conversion of 2-hydroxy-4-alkoxy-pyrimidine (Ⅱ,X=OCH_3 or OC_2H_5) into uracil (Ⅱ, X=OH). The change is represented as follows:2-Hydroxy-4-chloro-pyrimidine was reduced to 2-hydroxy-pyrimidine, m.p. 178-180° or m.p. 180-182°, by (a) the action of zinc dust in ethanol in presence of ammonium hydroxide and (b) by the catalytic reduction in presence of palladium-charcoal in ethanol.

    Quinazolone-4 was chlorinated with chlorine in glacial acetic acid,with ferric chloride ascatalyst.The reaction was carried out at different temperatures (39-100°),and with differentamount of chlorine (molar ratio of chlorine to quinazolone varying from 0. 92 to 1. 81) .Thechlorinated products were separated and purified by recrystallization from benzene,ethanol,aqueous ethanol,butanol and acetone,and were found to be 6-chloroquinazolone (m.p.268-269°),8-chloroquinazolone (m.p.300-302°) and 6,8-dichloroquinazolone...

    Quinazolone-4 was chlorinated with chlorine in glacial acetic acid,with ferric chloride ascatalyst.The reaction was carried out at different temperatures (39-100°),and with differentamount of chlorine (molar ratio of chlorine to quinazolone varying from 0. 92 to 1. 81) .Thechlorinated products were separated and purified by recrystallization from benzene,ethanol,aqueous ethanol,butanol and acetone,and were found to be 6-chloroquinazolone (m.p.268-269°),8-chloroquinazolone (m.p.300-302°) and 6,8-dichloroquinazolone (m.p.347-349°)respectively.Their identities were established by elementary analysis and mixed melting point testswith known synthetic compounds.The nature and relative amount of the chlorinated products were found to be influencedsomewhat by the conditions of chlorination.Roughly speaking,the conversion of quinazolonewas below 40% in most cases,and was higher than 50% only when the reaction was carriedout at higher temperatures (97-100°) and with higher molar ratios of chlorine to quina-zolone (above 1. 5) .Only under these latter conditions,6,8-dichloroquinazolone was obtained.In most of our experiments,the yield of 6-chloroquinazolone was much higher than that of8-chloroquinazolone,and in a few cases the latter was slightly more than the former.It wasalso found that under the same or even more drastic conditions used for the chlorination ofquinazolone,both 6-and 8-chloroquinazolone gave no dichloro derivatives.

    Some kinds of Chinese coal have been hydrogenated in the autoclave for catalyst studies.Under the condition:temperature 450°,initial hydrogen pres- sure 100 atm./20°,and reaction time 1 hr.,the conversion of Shenli coal of Fushun reaches or exceeds 95%,when SnC_2O_4+NH_4Cl,SnCl_2,tin ore+NH_4Cl, ZnCl_2,(NH_4)_2MoO_4,FeS,or sulfurized bogiron ore is used as catalyst. A time-saving“microautoclave”technique is developed and is recommended for the preliminary study of coal hydrogenation. In the range of temperature 400—450℃ and initial hydrogen pressure 50—100 arm.,the order of hydrogenation activity of the three series of catalysts studied is:tin>molybdenum>iron;for the conversion of asphaltene,the activity of tinhalide catalyst is also the highest. As shown in this investigation,the Shenli coal of Fushun is well amenable to hydrogenation,and its use in the production of aromatic compounds and liquid fuel is very prospective.
