Abstract
New fluorine containing 2-(fluoroaryl)-1H-indole-3-carboxaldehydes have been synthesized and subjected to reaction with thiosemicarbazide to give corresponding 2-([2- (fluoroaryl)-1H-indol-3-yl]methylene)hydrazinecarbothiamides which were cyclized in the presence of chloroacetic acid, sodium acetate and substituted benzaldehydes to 2-(fluoroaryl)-([5- (substituted benzylidene)-4-oxo-2-thiazolidinylidene]hydrazone)- 1H-indole-3-carboxaldehydes as potential antifertility agents. In preliminary screening, 2-(4'-fluorophenyl)- ([5-(methylene-3,4-dioxyphenyl)-4-oxo-2- thiazolidinylidene]hydrazone)-1H-indole-3-carbocaldehyde exhibited pronounced antifertility activity. All these new compounds have been characterized by analytical and spectral (IR, PMR, MS) studies.

Abstract
Reactions of various 3-aroylmethylene-indol-2-ones with hydrazine and phenylhydrazine under exactly similar conditions have been carried out. The reaction with phenylhydrazine has not been investigated earlier. It was found that although the reaction with hydrazine hydrate afforded a spiro derivative viz., spiro[3H-indole-3,3'-(3H)pyrazol]-2(1H)-one, that with phenylhydrazine yielded simply a hydrazone derivative. Representative spiro compounds have been screened for antifertility activity but none was found active at a dose of 10 mg/kg in adult female rats.

Abstract
Several fluorine-containing 3- aroylmethyl -3-hydroxyindol-2-ones (4a-g), 3- aroylmethyleneindol -2-ones (5a-g) and 3- aroylmethylindol -2-ones (6a-g) were synthesized from the corresponding fluorine-containing indole-2,3-diones and appropriate ketones. The compounds were characterized by spectral studies. Representative compounds of each series were tested on mice for CNS activities, viz. analgesic and anticonvulsant and the effects were also observed against amphetamine-induced stereotypy, on conditioned avoidance response and on potentiation of pentobarbitone sodium hypnosis. Of the compounds examined, the greatest degree of activity was observed in 3- aroyl - methyleneindol -2-ones with a pronounced unsaturation in the system.
