Some Low-Valent Organometallic Complexes of Pt-group Metals, Part-1:Complexes of Pd(0) and Pt (0)

Abstract

[M(pɸ₃)₄] (M = Pd or Pt) readily undergoes substitution reaction in dry benzene. Heterocyclic thioamides, 1-substituted tetrazoline- 5-thione, ethylene thiourea, 2-mercapto-3-substituted-quinazoline-4-one and substituted triazoles easily displaces two molecules of Pɸ₃ in dry benzene from [M(pɸ₃)₄]. However, all Pɸ₃ molecules could not be displaced. The same reaction is also carried out using isonicotinic acid hydrazide both four and six coordinated organometallic compounds were resulted.
