Abstract

Abstract The olefins mentioned in the title were copolymerized with CO in the presence of palladium catalysts modified with dicyclohexyl {(R)-1-[(S)-2-(diphenylphosphino) ferrocenyl] ethyl} phosphine. Productivities up to 95 g/(gPd· h) were achieved. The obtained copolymers were recovered in the pure, regio-und stereoregular polyketone structures3. The isotactic poly [2-benzyl-1-oxopropane-1, 3-diyl](3a) and its analogues 3b, c were found to ...
