Abstract
A process for preparing compounds of the series triphenylethanes, triphenylethylenes and triphenylethanes of the formula: ** (See formula) ** where R and R 'are each hydrogen, chloro or methoxy, n is zero or one and Z is C-pyridyl, which consists of mixing pyridyl-lithium or picolyl-lithium with a compound of the formula: ** (See formula) ** where R and R 'are those defined above, in an inert solvent at a temperature comprised between -60º C and + 80º C and hydrolyzing the resulting imine by mixing it with a diluted solution of mineral acid at 25-100º C.
