N2 - 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″′.
