compounds were obtained by reaction of the corresponding aminotroponimines with ZnPh2 and [ZnN(SiMe3)2}2], respectively. The new complexes were compared with the corresponding methylzinc complexes, which were previously reported, to study the influence of the substituents of the zinc atom in the catalytic hydroamination/cyclization reaction. In the presence of equimolar amounts of [PhNMe2H][B(C6F5)4] it was
