Insertions into azatitanacyclobutenes: New insights into three-component coupling reactions involving imidotitanium intermediates
Reaction of the titanium imido complexes [Ti(NR)(N2XylNpy)(L)] (N2XylNpy = MeC(2-C5H4N) {CH2N(3,5-C6H 3Me2)}2) with aryl acetylenes afforded the {2+2} cycloaddition products [Ti(N2XylN py){κ2-N(tBu)CH=CAr}] (Ar = Ph: 1a, Tol: 1b (Tol = 4-C6H4Me)). Complex 1a was found to insert sulfur and selenium a...
