Abstract

Several secondary phosphine oxides (SPOs, 2a-2d ) as well as 2a -chelated palladium complex 2a_Pd were employed in Catellani type reaction for the synthesis of 1-methyl-9 H -carbazole ( 4 ) from 2-iodotoluene and N -(2-bromophenyl)acetamide ( 3 ). The application of these ligands ( 2a-2d ) and palladium complex ( 2a_Pd ) in this reaction is beneficial in terms of increasing the yield of the major product, 4 . An elaborated mechanism was proposed to account for the observation of 4 as well as some side products, 5 , 6 , 7 , and 8 , via C-C and C-N bonds formation processes. [ABSTRACT FROM AUTHOR]
