Af. Hill et al., Phospha-alkyne hydro-osmiation: synthesis of [Os{kappa P-1,kappa P-1 '-P=CRP(=CHR)}Cl(CO)(PPh3)(2)](R = CMe3), CHEM COMMUN, (5), 1999, pp. 451-452
The reaction of [OsHCl(CO)(PPh3)(2)(BTD)] (BTD = 2,1,3-benzothiadiazole) wi
th P=CCMe3 provides the novel complex [Os{kappa(1)P,kappa(1)P'-P=CRP(=CHR)C
l(CO)(PPh3)(2)] (R = CMe3) which features both phospha-alkenyl and phosphaa
lkene donors within the same metallacycle.
