Mechanically activated solid-state synthesis of flavones by high-speed ball milling

An efficient, mechanically activated solid-state synthesis of flavones from 1-(2-hydroxyphenyl)-3-aryl-1,3-propanediones using high-speed ball milling is described. This method has notable advantages in terms of good yield, short reaction time, and neat conditions.

A facile synthesis of flavones catalysed by gallium(III) triflate

Ga(OTf)3 was explored as a novel catalyst for the cyclisation of 1-(2-hydroxyphenyl)-3-aryl-1,3-propanediones in nitromethane to flavones with excellent yields.

Reaction of 2'-Hydroxychalcone Dibromides with Me2SO

2'-Hydroxychalcone dibromides on treatment with Me2SO gave 2'-hydroxychalcone, 2'-hydroxy-3'- or 2'-hydroxy-5'-bromochalcone, flavone, monobrominated flavone, 6,8-dibromoflavone, 3-bromoflavone, and 3-, 6-, or 8-dibromoflavone.
