The transformation of arylcarboxaldehydes and/or - ketones 2 by three different routes into arylethylamines 3 and/or 4 is reported.According to the first route, the intermediate iminophosphonates 9 react through a classical PO-activated olefination.The second and the third involve the rearrangement of the iminophosphonates 9 into the vinylphosphoramidates 12.

The present invention provides a process for the preparation of 2-(thien-2-yl)- and 2-(thien-3-yl)-ethylamine derivatives of the general formula: STR1 in which R1, in the 2-, 3-, 4- or 5-position, is a hydrogen or halogen atom, a nitro, carboxyl, cyano or amino group, a linear or branched alkyl or alkoxy radical or a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or polysubstituted, the aminoethyl chain is in the 2- or 3-position, R2, R3 and R4, which are the same or different, are hydrogen atoms or heterocyclic or non-heterocyclic aromatic radicals, which are optionally mono- or polysubstituted, and Ar is a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or polysubstituted.
