Abstract

p-HO-Ph (Ph2) P (E)(E= S, 1b, Se, 1c) reacts with the diazonium salts [4-R-PhNN][BF4](R= H, Me, Et, iPr, tBu, NMe2, NO2) to afford the new compounds [1-HO-2-(4-R-PhNN)-4-Ph2P (E) C6H3](E= S, R= H, 2a; Me, 2b; Et, 2c; iPr, 2d; tBu, 2e; NMe2, 2f; NO2, 2g; E= Se, R= H, 2h; Me, 2i) in acceptable yield. Similarly m-HO-Ph (Ph2) P (S) 3 reacts with two molar equivalents of the diazonium salts [4-R-PhNN][BF4](R= H, Me, NMe2, NO2) to give the ...
