Abstract
Thiaxanthenol (XXVI) has been shown to react at room temperature in a mixture of glacicl.1 a c e t i c acid and ethyl alcohol w i t h many molecules containing hydrogen substitu- Led carbon, nitrogen and s u l f u r utoms of high electron deusity. (XXVI) reacted with cyenome thy1 derivhtives to afford 9-thiaxanthenyl cyanomethane derivutives (LXVIlla-e) throudh a condensation of reaction vgith the elenination of water. Thiaxanthenol reacted with phenol and some thiols namely, t h i o g l y c o l l i c acid, benzene thidand 2-merc~iptobenzoic acid to give phenyl thiaxanthenyl ethel- (LXIX), 9-thiaxanthenyl t h i o g l y c o l l i c a c i d (LXXa) , thiaxanthenyl phenyl sulphide (LXXb) , and 9-thiopheno (2-carboxy) thiaxanthene (LUc) , respectively. 9,9-thiaxanthenyl sulphide (LXXXVI) was prouuced through the reaction of dry hydrogen sulphide with thiaxanthenol (XXVI) . Oxidation of both 9-thiaxanthenyl thiogly-collic acid (LXXa) and 3,9-dithiaxanthenyl sulfide (LXXXVI) with hydrogen peroxide yielded the same product g-thiaxanthone- 10,lO-dioxide (LXXII) . 9-thiaxanthenyl phenyl sulfone-10,lO-dioxide (LXXVII) was produced by the oxidation of LXXb with hydrogen peroxide.
