Abstract

Diethylzinc reacts with hydroperchlorates of N-alkylated 1,3,5-triazacyclohexanes (R(3)TAC; R = methyl (Me), benzyl (Bz), isopropyl (Pr-i))and with the hydrotetrafluoroborate of 5-tris-(para-fluorobenzyl)-1,3,5-triazacyclohexane (FBz(3)TAC) to give the corresponding cationic zinc ethyl complexes [(R(3)TAC)Zn(Et)][X] (X = ClO4-, BF4-). Similar complexes were obtained from diethylzinc treated with [HNMe(2)Ph][BF4] or[HNMe(2)Ph][B(C6F5)(4)](Et(2)O) in the presence of R(3)TAC (R = Bz, FBz, s-1-phenylethyl (s-PhMeCH)). A product of decomposition of [(Bz(3)TAC)Zn(Et)][ClO4] was analyzed by X-ray diffraction. The structures of[({s-PhMeCH}(3)TAC)Zn(Et)][BF4] and [(FBz(3)TAC)Zn(Et)][BF4] were estimated using nuclear Overhauser enhancement spectroscopy. Protonolysisof diethylzinc with [HNMe(2)Ph][BF4] in the presence of nzyl-1,5,9-triazatricyclo[7.3.1.0(5,13)]-tridecane (BzTATC) yielded the complex [(BzTATC)Zn(Et)][BF4].
