conditions. The formation of the penicillin derivatives is stereoselective. The isocyanides CNCH(R)Fc (R=H, iPr, cHex) and CN(EtO2C)CCHFc react with [AuCl(PPh3)] to give the corresponding gold(I) complexes [AuL(PPh3)]A (L=ferrocenyl alkyl isocyanide, A=Cl or BPh4 when the reaction is carried out in the presence of Na[BPh4]). Cyclic voltammetry in aprotic medium shows that these complexes undergo a reversible
