Simultaneously, formation of boroxine 3 could be considered as borylene transfer to capture the oxygen atom from CO. The reaction of diborane(4) with tBu−NC afforded an azaallene, while the reaction with Xyl−NC furnished cyclic compounds by direct C−H borylations., ファイル公開:2019-05-22}, pages = {6109--6114}, title = {Reaction of B2(o-tol)4 with CO and Isocyanides: Cleavage of the C≡O Triple Bond and Direct C−H Borylations}, volume = {57}, year = {2018} }
