Abstract

Aziridine reacts spontaneously in THF at room temperature or below with the coordinated RNC ligand in some neutral and cationic isocyanide complexes of Pd(II) and Pt(II) to yield 5-membered cyclic diaminocarbene complexes, respectively. Reactions between thiirane and Pd(II) isocyanide complexes yield the corresponding cyclic amino-thiocarbene derivatives. In the presence of NaCl, oxirane is observed to react in 2-chloroethanol with some Pt(II) isocyanide complexes to form the corresponding 5-membered cyclic aminooxy carbene complexes. Also hydrido-alkyl-carbene derivatives were prepared by reaction of azetidine with some hydrido-alkyl-isocyanide compounds.These latter complexes react with triphenylphosphine eliminating H-Rx derived from Pt-Rx cleavage by NH.
