Abstract

Procedure for the preparation of 1,3-diazacyclopentene- (2) substituted in position 2 of the general formula **(See formula)** in which X means a halogen atom or a cyano group and means hydrogen, a lower alcohol group or a halogen atom, characterized in that in compounds of the general formula **(See formula)** in which R1 has the aforementioned meaning, the nitro group present is catalytically reduced to an amino group, the latter is diazotized, and the diazonium salt thus obtained is heated with monovalent copper halide or cyanide, optionally prepared "in situ", or, for the introduction of a fluorine atom into the phenyl nucleus, it is converted by reaction with fluoroboric acid to form the corresponding diazonium fluoroborate, and the latter decomposes by heating.
