摘要：

Mono(cyclopentadienyl)titanium neopentylidene complexes with bulky phosphinoalkoxide ancillary ligands were prepared via the corresponding dineopentyl complexes. The structure of 3b was determined by an X-ray analysis. Crystal data: Ti(eta(5)-C5H5)(CHMe(3))(PMe(2)-CH2C(O)-CMe(2)-o-C(6)H(4)CMe(2)), monoclinic, space group P2(1)/c (No. 14), a = 10.728(3) Angstrom, b = 12.881(4) Angstrom, c = 18.553(6) Angstrom, beta = 104.36(3)degrees, Z = 4, N-o = 3419, R = 0.045. The titanium alkylidene readily reacts with ethene, initially forming a metallacycle, while subsequent reactions produce a stable ethene complex. Reaction of the alkylidene with CO to form ketene derivatives was briefly studied.
