The invention discloses a one pot process for the arylation of β-dicarbonyl compounds. Particularly, the present invention discloses transition-metal-free, chemo-selective, one pot process for the C-arylation of malonamide esters having Formula I at room temperature provide temperature range to obtain the arylated compounds of formula II with good yield, wherein the arylated compounds are selected from mono-arylated compound and di-arylated compound or mixture thereof.

A facile, fluoride-induced transition-metal-free chemoselective α-arylation of β-dicarbonyl compounds (malonamide esters) at room temperature using aryne intermediates has been demonstrated. Selective mono- or diarylation and generation of a quaternary benzylic stereocenter have also been achieved. The methodology will be highly useful for the synthesis of a library of CNS depressant barbiturate drugs
