Phospha-alkyne hydro-osmiation: synthesis of [Os{κ1P,κ1P′-P
CRP(
CHR)}Cl(CO)(PPh3)2] (R = CMe3)
Abstract
The reaction of [OsHCl(CO)(PPh3)2(BTD)] (BTD = 2,1,3-benzothiadiazole) with PCCMe3 provides the novel complex [Os{κ1P,κ1P′-P
CRP(
CHR)Cl(CO)(PPh3)2] (R = CMe3) which features both phospha-alkenyl and phospha-alkene donors within the same metallacycle.
