TL;DR: In this article, the aminocarbene complexes (CO)5CrC(R1)N(R2R3)1[R1= H, Me, Ph, R2= Me, R 2R3=(CH2)5, R3 = Me, cyclopropyl] react with diphenylacetylene to give nitrogen ylides 5 which were fully characterized by an X-ray analysis carried out on 5a[(CO)3CrR2r3N(C16H10OR1)
Abstract: The aminocarbene complexes (CO)5CrC(R1)N(R2R3)1[R1= H, Me, Ph, R2= Me, R2R3=(CH2)5, R3= Me, cyclopropyl] react with diphenylacetylene to give nitrogen ylides 5 which were fully characterized by an X-ray analysis carried out on 5a[(CO)3CrR2R3N(C16H10OR1)–(R1= H, R2= R3=(CH2)5] and which lead, upon nitrogen to carbon migrations of alkyl groups R2 and R3, to the expected lactams (e.g.8 and 9) C16H10ONR1R2R3.

TL;DR: In this paper, alkyne(aminocarbene) complexes with enaminoketene coordinated to Cr(CO)3 and arene tricarbonyl chromium nitrogen ylides were characterized by X-ray analysis.
