SYNTHESIS OF NOVEL ORGANOBORON POLYMERS BY HALOBORATION POLYMERIZATION OF BISALLENE COMPOUNDS AND THEIR REACTIONS

Novel organoboron polymers were prepared by haloboration polymerizatri on of bisallene compounds. The polymers obtained have allylborane hali de units in their main chain and can be expected as a novel type of re active polymers. For example, the polymer prepared by haloboration pol ymerization between tribromoborane (1) and 1,2,10,11-dodecatetraene (2 b) was subjected to chain transformation reaction (dichloromethyl meth yl ether rearrangement) to give the corresponding polyalcohol or polyk etone. Haloboration-phenylboration polymerization of aliphatic bisalle nes by using diphenylbromoborane also gave the corresponding polymers.
