摘要:
                                WCl6 was reacted with excess allyltrimethylsilane in diethyl ether solution at low temperature. The main product in the reaction was shown to be WCl5(OEt2) which was isolated as black-green air- and moisture-sensitive crystals. WCl5(OEt2) was reacted with different Lewis bases, e.g. pyridine and 9-fluorenone to yield the new compounds WCl5 (pyridine) and WCl5(9-fluorenone). The latter most likely being an oxygen bonded complex.
