neutral intermetallic systems (CO)nM−Ga[X(L)2] (M = Cr, Mo, W, Fe; n = 4, 5; X = Cl, Me, Et; L2 = tmeda, dme, bipy, tBu-dab, thf2) (1−14) and (CO)5M-Al[X(L)2] (M = Cr, Mo, W; X = Cl, Et, iBu; L2 = tmeda, tmpda) (15−20, 23, 24). The chloro derivatives can be converted to the corresponding hydrido or tetrahydridoboranato species which is exemplarily shown by compounds 21 and 22. In the case of R2GaCl
金属羰基二价阴离子在 thf 中与第 13 族氯化物 XmECl3-m(E = Al、Ga;X = Cl、Me、Et、iBu;m = 0、1)反应生成单阴离子物质 [(CO)nM-EXmCl2-m ]- (M = Fe, Cr, Mo, W; n = 4, 5) 作为主要产物,在与非配位阳离子交换后可以作为无溶剂盐分离。在加入螯合路易斯碱(例如 tmeda、dme 和溶剂与二氯甲烷交换后,初级产物进行第二次盐消除反应,产生中性金属间系统 (CO)nM-Ga[X(L)2] (M = Cr, Mo, W, Fe; n = 4, 5; X = Cl, Me, Et; L2 = tmeda, dme, bipy, tBu-dab, thf2) (1−14) 和 (CO)5M-Al[X (L)2] (M = Cr, Mo, W; X = Cl, Et, iBu; L2 = tmeda, tmpda)
