Mono-η-cyclopentadienylchloro derivatives of niobium and tantalum and improved routes to mono-η-cyclopentadienyl-chloro, -oxochloro, and -oxo derivatives of molybdenum
Abstract
Simple synthetic routes are described for the compounds [M(η-C5H4R)Cl4]n(M = Nb or Ta, R = H, Me), [Nb(η-C5H4Me)2Cl2], [Mo(η-C5H4R)Cl4]n, [Mo(η-C5H4R)Cl2O], and [η-C5H4R(O)Mo(µ-O)2Mo(O)(η-C5H4R)].
