摘要
En 中文
Two coordinate boron cations are rare. Herein we report the synthesis of [RNSiMe2CH2]2BF (R = Dipp 3, 1-Ad 5) (Dipp = C6H3(iPr)2, Ad = C10H15) via the reaction of BF3 with the corresponding dilithiated diamides. Subsequent abstraction of fluoride provided the corresponding borinium salts, [(RNSiMe2CH2)2B][B(C6F5)4] (R = Dipp 6, 1-Ad 8). While the former was generated, the latter proved isolable and was crystallographically characterized. Abstraction of fluoride from [RNSiMe2CH2]2BF (R = Dipp, 1-Ad) (Dipp = C6H3(iPr)2, Ad = C10H15) provides the corresponding chelated borinium salts, [(RNSiMe2CH2)2B][B(C6F5)4].
