[2+3] Cycloaddition Reactions of Azido Metal Complexes and Crystal Structure of the Cycloadduct of (Ρh₃Ρ)₂Pd(Ν₃)₂ with Benzonitrile

Abstract

Cycloaddition reactions of (R 3 P) 2 M(N 3 ) 2 (M = Pd, Pt) with organic nitriles, thiocyanates, isothiocyanates, dimethylacetylenedicarboxylate and carbon disulphide are described; an X-ray analysis of the crystal structure of bis (5-phenyltetrazolato) -bis (triphenylphosphine) palladium (II) is summarised and related to isomerism of the complex in solution.
