【発明の名称】カルバミン酸誘導体の製造方法
Document Type and Number:
Japanese Patent JPH0617355
Kind Code:
B2
Abstract:
The invention relates to a process for preparing carbamic acid derivatives of formula: in which R1 or R2 denotes a hydrogen atom or a substituted or unsubstituted, saturated or unsaturated aliphatic, cycloaliphatic or heterocyclic radical, or R1 and R2 together form a ring, and Y denotes OR, SR, groups, R being a substituted or unsubstituted, saturated or unsaturated aliphatic or cycloaliphatic radical, or a substituted or unsubstituted aromatic radical, R3 and R4 denote a hydrogen atom or an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical or together form a ring, and R6 and R7 denote a saturated or unsaturated, substituted or unsubstituted aliphatic or cycloaliphatic radical, a hydrogen atom, an alkylthio radical or an alkyloxy radical. According to the process, a compound of formula is reacted with an alpha -halogenated derivative of formula at a temperature of -5 DEG to 150 DEG C. in the presence of an acceptor for hydrohalic acid. The carbamates, thiocarbamates or ureas obtained are very useful, especially as pesticides.
