Resumen:
Reaction of the complex fac-[Mn(CNtBu)-(CO)3{(PPh2)2C-H}] (1) with dimethyl acetylenedicarboxylate and methyl propiolate affords the compounds fac-[Mn(CNtBu)(CO)3{(PPh2)2CC(R)dC(R¢)-H}] (2a, R ) R¢ ) CO2Me; 2b, R ) H, R¢ ) CO2Me), as a result of regio- and stereospecific insertion of the alkynes into the C-H bond of the diphosphanylmethanide ligand, allowing highly selective metal-assisted synthesis of new functionalized diphosphane derivatives.
