Abstract

Metallation of 2-(Me₃Si)₂CHC₅H₄N (= RH) with LiBuⁿ in hexane yields RLi • RH, (1), whereas RH with LiBuⁿ and tmeda (tetramethylethylenediamine; 1 equiv.) in hexane affords RLi(tmeda), (2); the related 2-(Me₃Si)CH₂C₅H₄N (= R′H) with LiBuⁿ in a hexane-diethyl ether mixture gives [LiR′(OEt₂)₂], (3): compounds (1)–(3), shown by X-ray crystallography to have novel η³-aza-allyl ligand geometries, are regarded as models for the bonding in the products of metallation of systems CH₃-C(R″)=NR″′.
