Selective halogenation of 1-(2-hydroxyphenyl)-3-phenylpropane-1,3-diones using phase transfer catalysis and synthesis of 3-chloro- and 3-bromo-flavones
Makrandi,Shashi,Kumar, Surender
, p. 895 - 896 (2007/10/03)
Selective chlorination and bromination of 1-(2-hydroxyphenyl)-3-phenylpropane-1,3-diones have been achieved by their reaction with ammonium chloride/ammonium bromide and hydrogen peroxide in biphase medium using phase transfer catalysis.
