Synthesis of Some Novel Analogues of Phthalein Dyes: Phthal-as-eins
Chamoli, R. P.,Gupta, P. C.
, p. 777 - 779 (2007/10/02)
A number of novel phthalein dyes (V-X) have been synthesised by the condensation of phenols with 2-(p-bromobenzoyl)benzoic acid (Ia) and 2-(p-bromobenzoyl)tetrachlorobenzoic acid (Ib).These dyes, being unsymmetrically substituted phthalides where the cent
