The reasons for the reactivity increase toward acyl chlorides caused in aromatic amines by silylation are studied by quantum semiempirical and ub initio methods. Silylated amino groups adopt an sp2 planar geometry, in contrast to that observed in the unsilylated series, where a partially pyramidal s

## Abstract A semiempirical quantum‐mechanical study of structural and electronic parameters of aromatic diamines was performed using the method AM1. The diamines have been considered as condensation monomers, and the reactivities of both amino groups against acyl chlorides have been computed. The
