Abstract

The reaction of 2-diazo-1, 2-diphenylethanone (1) with 2-imino-1, 2-diphenylethanones 2 ae gave new N-substituted 3, 3, 4-triphenyl-4-benzoylazetidin-2-ones 3 ae, together with 1, 1', 2, 2'-tetraphenyl-2, 2'-azinodiethanone (4). Similar reaction of 1 with 2- iminoacenaphthenones 6 a, b yielded N-substituted 3', 3'-diphenyl spiro (acenaphthen-1- one-2, 4'-azetidin-2'-ones) 7 a, b and ketazine 4. Lithium aluminium hydride reduction of ...
