3-Phenyl-4-pseudohalocyclobutenediones 2, 3 are prepared from 3-halo-4-phenylcyclobutenediones.The thio- and selenoethers 4 and the thio- and selenoureas 5 are obtained from 2 and 3 as secondary products.The reaction products of 2a and 3a with aromatic and heteroaromatic 1,2-diamines are described.Action of chlorine on 3a leads to the chloroformimidoyl chloride 9.On treatment with bases the four-membered ring of 2a is cleaved.
