CARBENE COMPLEXES FROM COORDINATED BIS(DIPHENYLPHOSPHINO)METHANE - SYNTHESIS AND X-RAY STRUCTURE DETERMINATION OF THE REMARKABLE HETEROTRIMETALLIC DERIVATIVE [(FE(CNPH)4((PPH2)2C))2HG]I2
J. Ruiz et al., CARBENE COMPLEXES FROM COORDINATED BIS(DIPHENYLPHOSPHINO)METHANE - SYNTHESIS AND X-RAY STRUCTURE DETERMINATION OF THE REMARKABLE HETEROTRIMETALLIC DERIVATIVE [(FE(CNPH)4((PPH2)2C))2HG]I2, Journal of the Chemical Society, Chemical Communications, (9), 1993, pp. 740-742
The bis(diphenylphosphino)methanide complexes fac-[Mn(CNBut)(CO)3{(PPh
2)2CH}] la and [Fe(CNPh)4{(PPh2)2CH}]ClO4 lb react with HgI2 and KOH t
o give the heterotrimetallic bis(carbene)derivatives fac-[{Mn(CNBut)(C
O)3((PPh2)2C)}2Hg] 4a and [{Fe(CNPh)4[(PPh2)2C])2Hg]I2 4b, respectivel
y; the structure of 4b has been determined by X-ray analysis.
