Abstract The reaction of hydrazine-1, 2-bis (diphenylborane) with nitriles yields azines of borylamino ketones,(C 6 H 5) 2 B NH CR N N CR NH B (C 6 H 5) 2, which probably exist as coordinated bicyclic species. The interaction of the cited hydrazineborane with aldehydes and ketones appears to follow the same reaction path; however, due to the great affinity between boron and oxygen, derivatives of a C 6 H 5 BO species and azines ...
