Reaction of a molybdenum(0) dinitrogen complex containing a crown thioether with isocyanides. Formation of the extensively bent PhNC complex trans-Mo(PhNC)2(Me8[16]aneS4) and facile dealkylation of ButNC to give trans-Mo(CN)2(Me8[16]aneS4)(Me8[16]aneS4= 3,3,7,7,11,11,15,15-octamethyl-1,5,9,13-tetrathiacyclohexadecane)

Abstract

Reaction of trans-Mo(N₂)₂(Me₈[16]aneS₄) with PhNC gave trans-Mo(PhNC)₂(Me₈[16]aneS₄), the first extensively bent aryl isocyanide complex, while a similar reaction with Bu^tNC took place with dealkylation affording trans-Mo(CN)₂(Me₈[16]aneS₄); the X-ray crystal structures of both complexes have been determined.
