A chromium tricarbonyl complex featuring the 4,6-bis(diphenylphosphinomethyl)dibenzothiophene (PSPPh) ligand

Abstract

Abstract: The new PSP pincer ligand 4,6-bis(diphenylphosphinomethyl)dibenzothiophene (PSPPh) was prepared in 89 % yield. With this ligand, a solvothermal synthesis of a Cr complex of the type [Cr(κ3P,S,P-PSP)(CO)3] is described. The X-ray structure of this compound is presented. We demonstrate that the solvothermal synthesis technique provides a powerful, simple, and practical synthetic method resulting in a high isolated yield in a short reaction time.
