The imidotitanium alkyl cations [Ti(NtBu)(Me3[9] aneN3)R]+ (R = Me (3+) or CH 2SiMe3 (4+)) possess either a very weak α-agostic or β-Si-C agostic interactions, respectively, according to 13C and 29Si NMR and DFT studies; reaction of 4 + with iPrNCNiPr gives totally selective insertion into the Ti-alkyl bond; reaction of 3+ with AlMe 3 gives the first structurally characterised AlMe3 adduct of a transition metal alkyl cation (Me3[9]aneN3 = 1,4,7-trimethyltriazacyclononane).
