Thermolysis of o-nitro- and 2,4-dinitro-phenoxyacetic acids and related compounds
Abstract
The products of thermolysis of o-nitro- and 2,4-dinitro-phenoxyacetic acids and their sulphur analogues have been investigated. Predominant products from the former include 2H-1,4-benzoxazin-3(4H)-one and derivatives thereof, benzoxazoles, and related compounds. In general, decomposition of the sulphur analogues follows related pathways. The mechanisms of formation of some of the products are considered.
