Abstract

In the present work, we present a synthesis and crystal structures of two new CuCl π-complexes [Cu2(me-ath)2Cl2] (1), [Cu2(et-ath)2Cl2] (2) with 5-alkoxy-3-allyl-2- thiohydantoins, which were formed in situ from 3-allyl-2-thiohydantoin during electrochemically assisted synthesis in corresponding alcohol solutions (Scheme 1). As far as authors are concerned, similar reactions have not been previously submitted for this class of compounds and as a result, mechanism of this reaction is currently unstudied. Nevertheless, it is reasonable to suggest, that a crucial role in it is caused by the Fe ions used in a Fe(III)/Cu(0) source of Cu(I) ions, since, in similar systems with Cu(II)/Cu(0) source, such reaction hasn’t been observed.
