Kinetics and mechanism of certain benzoylation reactions under Vilsmeier-Haack conditions using benzamide and oxychloride in acetonitrile medium
Rajanna,Venkateswarlu,Satish Kumar,Umesh Kumar,Venkateshwarlu,Saiprakash
, p. 69 - 80 (2013)
Vilsmeier-Haack (VH) benzoylation reactions with benzaldehydes and acetophenones in acetonitrile medium obeyed second-order reaction kinetics. Under kinetic conditions, the reactions afforded benzoyl derivatives irrespective of the nature of oxychloride (
New syntheses of 3-aroylflavone derivatives; Knoevenagel condensation and oxidation versus one-pot synthesis

Two syntheses of 3-aroylflavones have been established. In the first synthesis the use of microwave irradiation led to an improvement in the yields of both the Knoevenagel condensation of β-diketones with aldehydes to afford 3-aroylflavanones and of their
A simple conversion of E-3-benzylideneflavanones to 3-benzoylflavones by chromic acid oxidation
Mallik, Asok K.,Chattopadhyay, Falguni
, p. 1947 - 1949 (2007/10/03)
Oxidation of E-3-benzylideneflavanones with CrO3/AcOH yields 3-benzoylflavones in moderate yield.
