Reaction of the boriranylideneboranes 1a , b , c with tetrahalogenodiboranes(4) leads to two types of products. In the case of 1a the cyclic tetraborylmethane derivatives 2a , a′ are formed in high yield, whereas 1b , c yield the isomeric linear diborylmethyleneboranes 3b , c . Compound 2a reacts with diethylamine, (dimethylamino)trimethylsilane, and lithium pyrrolidinide to give the 1,3‐diboretanes 4a , b , c . The composition of the products was determined from spectroscopic data and X‐ray structure analyses of 2a , 3c , 4a , and 4c .
