## Abstract Fully aromatic poly(heterocyclic imides) of high molecular weight were prepared by the cyclopolycondensation reactions of aromatic diamines with new monomer adducts prepared by condensing orthodisubstituted aromatic diamines with chloroformyl phthalic anhydrides. The low‐temperature sol
Tris(2,6-diphenylphenoxide) (ATPH). -1,6-Addition of silyllithium reagents to aromatic carbonyl compound ATPH complex and following enolate capture with an appropriate electrophilic reagent leads to functionalized allylsilanes shown in the scheme. In the reaction of (I), aromatic silylated products
