Usage

General Description

1,2,3,4,5-Pentachloro-6-ethoxybenzene, also known as PCEB, is a synthetic chemical compound that belongs to the class of chlorinated aromatic hydrocarbons. It is a white solid which is insoluble in water and has a faint odor. PCEB has been used as a pesticide, specifically as a fungicide to protect crops. It has been found to be toxic to aquatic organisms and harmful to the environment. PCEB is also considered to be a potential human carcinogen, with exposure linked to liver and kidney damage. Due to its toxic properties, PCEB has been subject to regulation and restriction in certain countries.

SNAAP sulfonimidate alkylating agent for acids, alcohols, and phenols 1

Stable, crystalline ethyl N-tert-butyl-4-nitrobenzenesulfonimidate has been prepared in high yield by direct O-ethylation of N-tert-butyl-4- nitrobenzenesulfonamide with iodoethane and silver(I) oxide in dichloromethane. This sulfonimidate directly ethylates various acids to esters; the stronger the acid, the faster it alkylates and in higher yield. It readily ethylates alcohols and phenols to ethers at room temperature in the presence of tetrafluoroboric acid catalyst without molecular rearrangements or racemization. We have defined these reactions as SNAAP alkylations: [substitution, nucleophilic of acids, alcohols and phenols]. The hard sulfonimidate alkylating agent is chemoselective, preferring oxygen > nitrogen > sulfur. The sulfonamide byproduct of alkylation is readily recycled to the sulfonimidate.
