In the reaction of tetravinyltin with boron tribromide, mercury has been found to exhibit a twofold effect: (a) it ensures the utilization of all four organic groups for the conversion of the boron trihalide to an organodihalogenoborane and (b) one notes the complete absence of organoboron by-products. As a result, the isolation and characterization of vinyldibromoborane was accomplished. Reactions of the latter compound with various amines have been studied and B-vinylated bisaminoboranes, 1,3,2-diazaborolidines, and borazines have been prepared. B-Vinylation does not appear to influence the electronic nature of the B-N bond to any appreciable degree.
