## Abstract 1,2,4โTriazinโ5(2__H__)โones 1 react as well with phenols, resorinol and its dimethyl ethers, as with dimethyland diethylaniline, yielding 6โarylโ1,6โdidydroโ1,2,4โtriazinโ5(2__H__)โones 2, 4โ8, 12โ15. Oxidation of the 1,6โdihydroadducts 2a,b gives the corresponding 3โarylโ6โhydroxyphen
The first example using manganese(Hi) acetate in the reaction of I,I--diarylethenes with ยข~-mercaptoketones was examined. A mixture of the ethenes and ct-mercaptoketones was treated with manganese(HI) acetate in acetic acid, affording cycloaddifon products in moderate yields, together with substitut
