英文摘要 | The reactions of SiF□/SiF□ with amines, phosphines and various halomethanes were studied. The results show that in the presence of strong Lewis base (Et□N, HNEt□, PR□, PR□Cl), SiF□ inserts initially into SiF□ to form Si□F □, which was followed by subsequent reactions leading to products containing SiF □ groups. This is the first report of the insertion of SiF□ into SiF□. When the reactants were a weaker base (such as RPCl□, CX□Br, X=F, Cl), insertion of SiF □ into P-Cl and C-Br bonds became predominant. |
