Naphthylmethyl acetates 1a and 2a were substituted by morpholine in DMPU in the presence of 2 mol% of [Pd(dba)(2) + 15 dppe] to give products 9-10 in 66-70% isolated yield. In DMF in the presence of benzylamine, N,N-dimethylnaphthylmethylamines 11-12 were produced in 78-85% isolated yield. Copyright (C) 1996 Elsevier Science Ltd

Sodium dimethyl malonate reacted with naphthylmethyl and 1-naphthylethyl alcohol derivatives in DMF at 20-80-degrees-C, under palladium(0) / phosphine catalysis. to give the substitution products dimethyl naphthylmethyl- and 1-naphthylethylmalonates. respectively, in good (75-83%) yield.
