Halides of boron, germanium, phosphorus, and arsenic react with lithio-aminofluorosilanes (1a-e) with elimination of lithium halide and substitution (to 2a, b, 3c, 4b, 5b, 5d, 6b).Depending on the bulkiness of the substituents and the reaction conditions, halosilanes are also cleaved off and four-membered rings (8d, 10b, 11b, 13b, 14b) are formed.The reaction of 1e with (Me3Si)2NPF2 leads to the formation of the aminoiminophosphane 9e.A 1,3-migration of a silyl group from the alkyl- to the arylamino-nitrogen is observed in this reaction. 5d reacts with lithiated (2,4,6-trimethylphenyl)(trimethylsilyl)amine to give 15d and LiF.The aminoiminophosphane 16d is obtained by thermal difluorosilane elimination from 15d.An aminoiminodifluorophosphane (12b) is formed in the reaction of 1b with PF5, isobutene, tert-butyldifluorophenylsilane, and LiF being claved off.
