Abstract
a : b - (p : p1 - Dihydroxydiphenyl) - a : b - di - lower alkyl ethylenes are obtained by converting a p-hydroxy-phenyl-lower alkyl ketone by treating with sodium amalgam in alkaline medium into the corresponding pinacol, treating the pinacol with a dehydrating agent to obtain the corresponding pinacoline, treating this latter with an alkali metal and an alcohol to obtain the corresponding pinacoline alcohol and reacting the pinacoline alcohol with a dehydrating agent, particularly a mineral acid. a : b - (p : p1 - Dihydroxydiphenyl) - a : b - di - lower alkyl ethanes are obtained (a) by hydrogenating the corresponding ethylenic compound obtained as above; (b) by converting a p-hydroxy-phenyl-lower alkyl ketone as above into the pinacoline alcohol, and treating this with hydrogen iodide, advantageously in conjunction with red phosphorus. In all cases, the expression "lower alkyl" represents an alkyl group containing not more than five carbon atoms. Suitable agents for dehydrating the pinacoline alcohols are halogen hydracids, especially hydrogen chloride or bromide. Both the saturated and unsaturated products are oestrogenic. In examples: (1) p-hydroxypropiophenone, in aqueous caustic soda, is shaken with sodium amalgam and the free pinacol, obtained by adding glacial acetic acid, is treated, in ether, with gaseous hydrogen chloride, the resulting pinacoline being reduced to the corresponding pinacoline alcohol by sodium and alcohol, prior to saturation, in ether, with hydrogen chloride to obtain a : b -(p : p1 - dihydroxydiphenyl) - a : b - diethyl - ethylene; (2) the pinacoline alcohol of (1) is heated in glacial acetic acid with hydriodic acid and red phosphorus to obtain a : b -(p : p1-dihydroxydiphenyl) - a : b - diethylethane; (3) the product of (1) is reduced with hydrogen iodide and red phosphorus in glacial acetic acid to obtain the product of (2).
