The [{MeC(CH2PPh2)3}Re(CO)2. auxiliary has been found to activate 1-ethynyl-1-cyclohexanol and 1-phenyl-2-propyn-1-ol yielding a variety of h1-carbon ligands, which includes hydroxyvinylidene, alkenylvinylidene, alkoxycarbene, h1-Csp-enynyl, secondary allenylidene, acyl, hydroxycarbene and alkoxycarbene groups. The reactivity of the allenylidene complex [{MeC(CH2PPh2)3}Re(CO)2{C.C.C(H)Ph}]. toward water and methanol has been investigated.

Abstract
The [{MeC(CH2PPh2)3}Re(CO)2. auxiliary has been found to activate 1-ethynyl-1-cyclohexanol and 1-phenyl-2-propyn-1-ol yielding a variety of h1-carbon ligands, which includes hydroxyvinylidene, alkenylvinylidene, alkoxycarbene, h1-Csp-enynyl, secondary allenylidene, acyl, hydroxycarbene and alkoxycarbene groups. The reactivity of the allenylidene complex [{MeC(CH2PPh2)3}Re(CO)2{C.C.C(H)Ph}]. toward water and methanol has been investigated.File in questo prodotto:
