Abstract:
Reactions of LiCFCF2 with the boron electrophiles BCl(OMe)2, BCl2(OMe), BCl3, and CF2CFB(OMe)2 were studied. The nucleophilic addition of LiCFCF2 to BCl(OMe)2 (2:1) and BCl2(OMe) (3:1) resulted in formation of a mixture of Li[(CF2CF)nB(OMe)4-n] salts, which were converted to K[(CF2CF)nBF4-n] (n = 1−4) using aqueous K[HF2]. The salt K[(CF2CF)4B] was prepared from BCl3 and LiCFCF2 (excess) and subsequent treatment with aqueous KF in 76% yield. The salt K[(CF2CF)2BF2] was synthesized by reacting (trifluorovinyl)dimethoxyborane with LiCFCF2 and subsequent substitution of methoxy by fluorine. K[(CF2CF)3BF] was obtained by the reaction of (CF2CF)3B with KF.
