NITROMETHYLENE DERIVATIVES OF NITROGEN CONTAINING HETEROCYCLIC COMPOUNDS

摘要

A pesticidal nitromethylene derivative of the formula in which R is a hydrogen atom or a lower alkyl group, m is 2, 3 or 4, and n is 0, 1, 2 or 3, is produced by reacting a compound of the formula in which R' each independently is a lower alkyl group, or together are an alkylene group forming a ring with the adjoining sulfur atoms.
