PALLADIUM-CATALYZED TRANSFORMATION OF ARENEDIAZONIUM SALTS TO ACYL ARENES BY ORGANOTIN COMPOUNDS AND CARBON MONOXIDE

Article abstract of DOI:10.1246/cl.1982.35

Arenediazonium salts (ArN2X; Ar=2-Me-C6H4, 3-Me-C6H4, 4-Me-C6H4, 2-Cl-C6H4, 4-Cl-C6H4, 4-Br-C6H4, 4-I-C6H4, 3-NO2-C6H4, 4-NO2-C6H4, and C6H5; X=BF4 and PF6) were effectively transformed to acyl arenes (ArCOR; R=Me, Et and Ph) in good yields (55-90percent) by R4Sn and CO under palladium catalysis.
