Reactions of chloro bridged palladium compounds with di- and tripeptide esters give (Et3P)(Cl)2Pd(NH2CHR1CONHCHR2CO2CH3) and the N,N′-chelate compounds (Et3P)- (Cl)Pd(NH2CH2CONCHR1 CO2R2), [C6H4CH 2NMe2(C,N)]Pd(NH2CH2CONCH2CO2Et) and (Et3P)Pd(gly-gly-glyOMe-2H+). The structure of (Et3P)(Cl)Pd(gly-alaOMe-H+) was determined by X-ray diffraction analyses. Attempts to form open chain peptides from α-amino
