Aminolysis of Triphenylantimony Dicarboxylates and Its Application to Catalytic Amidation

Article abstract of DOI:10.1246/cl.1986.1901

Triphenylantimony dicarboxylates (Ph3Sb(O2CR)2, where R=Me, CF3, Ph and CH2NH-Z) readily reacted with amines (R'NH2, where R'=n-C6H13, s-Bu, C6H11, and Ph) to afford corresponding amides and triphenylstibine oxide in fairly good yields.The amidation of RCO2H with R'NH2 was also catalyzed by the organoantimony compounds.
