High oxidation state bromocarbyne complexes†
Abstract
Bromination of the carbyne complexes [W(CR)Br(CO)2(dcpe)] (R = Ph, SiPh3; dcpe = 1,2-bis(dicyclohexylphosphino)ethane) provides high oxidation state derivatives [W(CPh)Br3(dcpe)] and [W(CBr)Br3(dcpe)], the latter via an unprecedented bromodesilylation process.
