摘要：

The highly labile half-sandwich alkyl complex [Y(eta (5):eta (C5Me4SiMe2NCMe3)-C-1)(CH2SiMe3)(THF)] smoothly undergoes a-bond metathesis with furan and thiophene in pentane to give tetramethylsilane and the sparingly soluble complexes [Y(eta (5):eta (1)-C5Me4SiMe2NCMe3)(mu -2-C4H3X)](2) (X = O, S). They dissolve in THF to give the THF adducts [Y(eta (5):eta (1)-C5Me4Si- Me2NCMe3) (2-C4H3X)(THF)(n)]. Pyrrole reacts with [Y(eta (5):eta (1)- C5Me4SiMe2NCMe3) (CH2SiMe3)(THF)] to give the Lewis base-free pyrrolide [Y(eta (5):eta (1)-C5Me4SiMe2NCMe3)(NC4H4)](n).
