A polymer-palladium complex prepared from palladium (Ⅱ) chloride and poly-γ-aminopropylsiloxane suported on fumed silica is very active for hydrogenation of olefins in proper solvents at 30℃ tinder an atmospheric hydrogen pressure. The rates of hydrogenation of olefins by the polymer complex are found to be markedly affected by the palladium content in the polymer complex.

Two new polytriazines: poly [2-methyl-4,6-(4',4" -diphenylene)-1,3,5-triazine] (Ⅰ) dan Poly [2-phenyl-4, 6-(4', 4"-diphenylene)-1, 3, 5-triazine] (Ⅱ) were synthesized from the solution condensation of biphenyl-4, 4'-diamidine dihydrochloride with acetic anhydride and biphenyl-4,4'-diamidine with benzaldehyde respectively. These two polymers were characterized by TGA, DTA, elemental analysis and IR spectroscopy. They exhibited good thermal oxidative stability as shown by the fact that the powders of these polymers...

Two new polytriazines: poly [2-methyl-4,6-(4',4" -diphenylene)-1,3,5-triazine] (Ⅰ) dan Poly [2-phenyl-4, 6-(4', 4"-diphenylene)-1, 3, 5-triazine] (Ⅱ) were synthesized from the solution condensation of biphenyl-4, 4'-diamidine dihydrochloride with acetic anhydride and biphenyl-4,4'-diamidine with benzaldehyde respectively. These two polymers were characterized by TGA, DTA, elemental analysis and IR spectroscopy. They exhibited good thermal oxidative stability as shown by the fact that the powders of these polymers suffered 5.4%, 2.4% weight loss after isothermal aging in air at 300℃ for 200 hours. The decomposition temperature of (Ⅱ) was 583℃ in air and 590℃ in N2. In comparison, the linear poly-1,3,5-triazine as mentioned above were soluble in concentrated sulfuric acid, phosphoric acid and trifluoroacetic acid whereas the crosslinked poly-l,3,5-triazines which have been reported in the literature were insoluble and infusibleIt is interesting that these polymers can be formed into complexes with PdCl2. as determined by X-ray photoelectron spectroscopy (XPS). The polymer complex (Ⅲ) PdCl2, where (Ⅲ) is poly [2-methyl-4,6-(1,4-phenylene)-1,3,5-triazine], possesses catalytic activity for hydrogenation.

The vinylic hydrogen substitution reaction with aryl halides, which is known as the Heck reaction, is an important reaction for the formation of carbon-carbon bond in the field of organometallic chemistry. In 1982, Spencer reported that the substitution reaction can be carried out with aryl halides promoted by homogeneous palladium complexes and thus extended the scope of the polymer-bound palladium complexes for the decarbo-nylarylation were investigated.

The vinylic hydrogen substitution reaction with aryl halides, which is known as the Heck reaction, is an important reaction for the formation of carbon-carbon bond in the field of organometallic chemistry. In 1982, Spencer reported that the substitution reaction can be carried out with aryl halides promoted by homogeneous palladium complexes and thus extended the scope of the polymer-bound palladium complexes for the decarbo-nylarylation were investigated. It was found that the activities of poly-mer-bound complexes are comparable to those of their homogeneous counterparts. Among these catalysts examined, the polymer-bound palladium complexes containg sulphur are more active and more stable than thatcon-taing phosphine, amine and nitrile. possible side reactions were also studied. The factors which caused the catalyst deactivation were discussed and the influence of experimental parameters on the reaction was investigated as well.
