title: Three different product types from reactions of lithiated cyclic aminals with trivalent organometal chlorides.
abstract: The reaction of 2-lithio-1,3,5-trimethyl-1,3,5-triazacyclohexane with YCp(2)Cl leads to the formation of a donor-functionalised mono-anionic amide ligand, 1,3,5-trimethyl-2-(methylamidomethyl)-1,3,5-triazacyclohexane, bonded to the YCp(2) unit. The reaction involves a cleavage of the 1,3,5-triazacyclohexane ring and such a cleavage is also observed in the analogous reaction with (Me(3)C)(2)GaCl, where a MeN[double bond, length as m-dash]CH(-) fragment is formed. No such cleavage occurs in the reaction of the related dilithiated bicyclic bis(3-methyl-1,3-diazacyclohex-1-yl)methane with YCpCl(2).3thf, which affords a mixed lithium-yttrium organyl.
