Hydroboration polymerization. 2. Synthesis of organoboron polymers by the reaction between diyne and thexylborane

The polyaddition between a terminal diyine such as 1,7-octadiyne and thexylborane (1) yielded a polymer containing 20 % branched structure due to the hydroboration of vinylborane units in the main chain of the polymer. As the result of the crosslinking reaction, gelation was observed when an excess amount of 1 was used. The gel dissolved by the treatment with methanol. When an internal diyne such as 3,9-dodecadiyne was used as a monomer, no gelation was observed even in the presence of an excess amount of 1.

Reactions of organoboron polymers prepared by hydroboration polymerization

Organoboron polymers consisting of carbon-boron bonds in the main chains were prepared by hydroboration polymerization of various dienes with thexylborane. These polymers were reacted with α-furyllithium followed by treatment with acetic acid to give the corresponding poly(alcohol)s. This conversion includes the migrations of two polymeric main chains from boron atom to carbon and the reductive cleavage of carbon-boron bonds in the resulting boron-containing polymers. The structures of the poly(alcohol)s obtained were characterized by 1H-NMR in comparison with that of model compound, which was prepared by the reaction of dioctylthexylborane with α-furyllithium followed by reductive treatment. The organoboron polymer prepared from 1,7-octadiene and thexylborane was also reacted with dichloromethyl methyl ether followed by acidolysis to form hydrocarbon polymer without obvious scission of polymeric main chain.
