Reaction of nucleophiles with alkoxycarbene complexes of chromium: a general access to polycyclic substituted butenolides
摘要:
A series of new substituted butenolides has been obtained either by reacting alkynylalkoxycarbene complexes 3 with simple nucleophiles such as metal hydrides, metal alkoxides and metal alkyls, or by reacting simple alkoxycarbene complexes 6 with more elaborate nucleophiles such as metal alkynolates or metal alkynyls.

The reduction of H2Os3(CO)10S or HOs3(CO)10(O2CMe) with KBH(OPr-i)3 at low temperatures yields unstable formyl complexes which have been identified by 1H NMR spectroscopy; at higher temperatures conversion into stable hydridoanions is observed.
在低温下用KBH(OPr-i)3还原H 2 Os 3(CO)10 S或HOs 3(CO)10(O 2 CMe)会生成不稳定的甲酰基络合物,已通过1 H NMR光谱鉴定;在较高温度下,观察到转化为稳定的氢阴离子。
