Known Appli­ca­tion

SPhos can be used as lig­ands for the fol­low­ing reac­tions : • Pal­la­di­um-cat­­a­lyzed Suzu­­ki-Miyau­ra cross-cou­­pling reac­tion between Boc-pro­­tec­t­ed aminomethyl tri­flu­o­rob­o­rate and aryl chlo­ride or het­eroaryl chlo­ride to form the cor­re­spond­ing Aminomethyl aro­mat­ic hydro­car­bons. • Pal­la­di­um-cat­­a­lyzed Suzu­­ki-Miyau­ra cross-cou­­pling reac­tion between 4-methyl sub­sti­tut­ed piperidinyl zinc reagent and dif­fer­ent aryl or het­eroaryl iodides to form var­i­ous sub­sti­tut­ed piperidines. • Intramol­e­c­u­lar Suzu­­ki-Miyau­ra cou­pling dur­ing the mul­ti-step syn­the­sis of ric­cardin C to form an 18-mem­bered macro­cy­cle. Used with pal­la­di­um to pro­duce a high­ly active cat­a­lyst for C-N bond for­ma­tion. High­ly ver­sa­tile lig­and for Suzu­­ki-Miyau­ra cou­pling reac­tion ; aryl chlo­ride, ster­i­cal­ly hin­dered diaryl, het­ero­di­aryl compounds.
