某些有机钨卤化物RC~5H~4(CO)~3WX(R=MeCO, MeO~2C, EtO~2C; X=Cl, Br, I)的合成及结构鉴定

通过酮基或酯基官能团取代的环戊二烯基(三羰基)钨钠 RC~5H~4(CO)~3WN(R=MeCO, MeO~2C, EtO~2C 与I~2、Px~3(X=Cl、Br、I), PhPCl~2, p-MeC~6H~4PCl~2或MeAsI~2 反应, 结果得到8个含相应官能团的有机钨卤化物。用X射线衍射法鉴定了其中 R=MeCO, X=Br的单晶分子结构, 晶体属单斜晶系, 空间群P~21。

Synthesis and identification of some organotungsten halides RC~5H~4-(CO)~3WX(R=MeCO, MeO~2C, EtO~2C; X=Cl, Br, I)

The title organotungsten halides were synthesized via the reactions of RC5H4(CO)3WNa with I2, PX3 (X = Cl, Br, I), PhPCl2, p-CH3C6H4PCl2 or MeAsI2. The single crystal mol. structure with R = MeCO, X = Br) was determine by x-ray diffraction.
