资源简介：
The successive treatment of [Mo(CBr)(CO)2{HB(pzMe2)3}] (1; pz = pyrazol-1-yl) with nBuLi and B(OR)3 (R = Me, iPr) affords, via the lithiocarbyne complex [Mo(CLi)(CO)2{HB(pzMe2)3}] (2), the boratocarbynes Li[Mo{CB(OMe)3}(CO)2{HB(pzMe2)3}] (R = Me, Li[3a]; R = iPr, Li[3b]). The salt Li[3b] readily eliminates LiOiPr to afford the neutral boryl carbyne [Mo{CB(OiPr)2}(CO)2{HB(pzMe2)3}] (4b). The analogous boryl carbyne [Mo{CB(OMe)2}(CO)2{HB(pzMe2)3}] (4a) on treatment with K[HF2] and 18-crown-6 (18C6) provides the structurally characterized difluoro(methoxy)boratocarbyne salt [K(18C6)][Mo(CBF2OMe)(CO)2{HB(pzMe2)3}] ([K(18C6)][6]).
