Özet:

 

A series of new aminophosphines [Ph22_{2}PHN-C66_{6}H44_{4}-R, where R = ooo-SH (\textbf{4a}), mmm-SH (\textbf{4b) or }ppp-SH (\textbf{4c})] were readily synthesized from cheap starting materials by the phosphorylation reaction of ooo, mmm, and ppp-aminothiophenols with Ph22_{2}PCl in the presence of triethyl amine. The new compounds were characterized by NMR and IR spectroscopy and microanalysis. In addition, aminophosphine ligands--palladium systems were investigated as precatalysts in C--C coupling reactions. Compounds \textbf{4b} and \textbf{4c }were proved to be excellent catalysts for Suzuki and Heck cross-coupling reactions.
