Abstract

The reaction of (Et 3P) 2Pd(μ-S)Ge[N(SiMe 3) 2] 2 (2) with paraformaldehyde under photolytic conditions results in the insertion of formaldehyde into the Pd-Ge bond, with bond cleavage, to give (Et 3P) 2Pd(μ-S) (μCH 2O)Ge[N(SiMe 3) 2] 2 (3). Subsequent addition of CO to 3 results in migratory insertion into the Pd-C bond, followed by rapid reductive elimination to regenerate the Pd 0 metal center and give a unique five-membered organic heterocycle, Ge[N(SiMe 3) 2] 2-SC(O)CH 2O (6). The X-ray crystal structure of the dppe (dppe = bis(diphenylphosphino)-ethane) derivative of 3, (dppe)Pd(μ-S)(μCH 2O)Ge[N(SiMe 3) 2] 2 (4), is reported.
