Primary amines are acetylated in high yield while secondary bulky amines and aniline are obtained in low yield. A tentative mechanism is proposed. INTRODUCTION.
of Yb(OTf)3 is enough to complete the reaction and the catalyst can recovered and reused easily without any loss of activity. Although the detailed mechanism.
This is a potentially useful green chemical transformation where reaction takes place in Amines; acetyl chloride; brine; sodium acetate; triethyl amine.
