Three new anilido-oxazolines, ortho-C6H4(NHAr′)(4,4-dimethyl-2-oxazoline) [Ar′ = 2,4,6-trimethylphenyl, HNPhTriMeOxa (1); 2,6-diisopropylphenyl, HNPhDiiPrOxa (2); 2-methoxyphenyl, HNPhOMeOxa (3)], have been prepared. Reactions of 1 or 2 with one molar equivalent of ZnEt2 in tetrahydrofuran or hexane solution give the zinc ethyl complexes (NPhTriMeOxa)ZnEt (4) and (NPhDiiPrOxa)ZnEt (5). The dinuclear zinc benzyloxide complexes, [(NAr′Oxa)Zn(µ-OBn)]2, [Ar′ = 2,4,6-trimethylphenyl, (6); 2-methoxyphenyl, (7)], were synthesized by the reaction of 4 with one molar equivalent of benzyl alcohol in tetrahydrofuran solution (for 6) or by treatment of 3 with one molar equivalent of ZnEt2 in tetrahydrofuran solution followed by the addition of one molar equivalent of benzyl alcohol (for 7). The molecular structures are reported for compounds 6 and 7. Their catalytic activities toward the ring opening polymerization reactions are under investigation.
