However, all compounds having the pyridyl and nitrogen in a cis relationship have been named the Z isomer.(biphos) produced a mixture of E and 2 isomers of 4. The amination was usually rapid at 55" C, and in most cases the reaction was completed within 1 h. Results from amination of some different acetates 3 are shown in Table I. The acetate 3 was completely unreactive toward amine in the absence of the palladium catalyst. Thus ...
