[formula: see text] The first general intermolecular C-N bond-forming reactions betweenarylhalides and amides were realized using a palladium catalyst with Xantphos as the ligand. Aryl triflates, carbamates, and sulfonamides are also viable substrates for the amidations, which proceed at 45-110 degrees C with 1-4 mol% of Pd catalyst in 66-99% yields and exhibit good functional group compatibility
Pharmaceutical compositions for inhibiting the aggregation of erthyrocytes or thrombocytes which include phenylamides which conform to the formula: ##STR1## with R.sub.1-6, X, A and B being as defined. Processes for the preparation of novel phenylamides coming within the above formula are also discussed.
