Abstract

W(CPh)Cl(CNCMe₃)₂(CO)₂ was prepared by reaction of W(CPh)Cl(CO)₂(py)₂ with CNCMe₃ in CH₂Cl₂. W(CPh)I(CNCMe₃)₂(CO)₂ was prepared by sequential reaction of W(CPh)Cl(CO)₂(py)₂ with NaI in THF and with CNCMe₃ in CH₂Cl₂. Reaction of W(CPh)Cl(CNCMe₃)₂(CO)₂ with pyrrole-2-carboxaldehyde methylimine in the presence of KOH in THF gives the ketenyl complex K[W(C₆H₇N₂)₂(PhCCO)(CO)]. Reaction of W(CPh)I(CNCMe₃)₂(CO)₂ with NaS₂CNEt₂ in THF gives a mixture of products, of which Na[W(PhCCO)(S₂CNEt₂)₂(CO)] is the main product. Reaction of W(CPh)Cl(CNCMe₃)(CO)(PMe₃)₂ with NaS₂CNEt₂ in THF leads to the formation of [W(PhCCO)(S₂CNEt)₂(CO)(PMe₃)₂] and [W(CPh)(S₂CNEt₂)(CO)(PMe₃)₂] as the main products.
