The 2-indenylidene chloropalladate {PdCl[Ind(Ph2P=S) 2]}(n Bu4N): A versatile pincer complex with "innocent" and "noninnocent" behavior

The chloropalladate pincer complex {PdCl[Ind(Ph2P=S) 2]}(nBu4N) (2) has been prepared, and its reactivity has been thoroughly investigated. Alkyl halides such as iodomethane and benzyl chloride react at the electron-rich 2-indenylidene moiety, leading to the 2-indenyl pincer complexes {PdI[Ind(Me)(Ph2P=S)2]} (3) and {PdCl[Ind(Bn)(Ph2P=S)2]} (4), respectively. The ligand backbone is also involved in the reaction of 2 with the electron-deficient alkyne MeCO2C≡CCO2Me. Formally, one of the pincer ligand side arms is elongated and the original complex 5, featuring three fused metallacycles, is obtained. Nucleophiles such as PPh3 and NHCy 2 also react readily with 2, to give the corresponding 2-indenylidene complexes by displacement of the chloride at Pd. In addition, treatment of 2 with PhC≡CLi affords {Pd(C≡CPh)[Ind(Ph2P=S) 2]}(nBu4N) (8), the first alkynylpalladate to be isolated. All the new compounds have been characterized by multinuclear NMR spectroscopy and mass spectrometry. The structures of complexes 3, 5, and 8 have been further analyzed by means of X-ray diffraction studies.
