PREPARATION OF NUCLEAR CHLORINATED COMPOUNDS

摘要

Chloro-aromatic compounds of the formula wherein R is CF3, OCF3, OC2F5, CN, NCO, or COCl, m is 0, 1 or 2; n is 0, 1 or 2; and q is 1 or 2; q + m + n is less than 6; are prepared by the vapor phase chloro-denitration reaction of a chlorinating agent with a nitro-aromatic compound of the formula where R, m, n and q are as defined above.
