Improved Halogenation of Methyl Aromatics and Methyl Heteroaromatics: Unexpected Reactivity of Tetrahalogeno-diphenylglycolurils
Moretti, Florian,Poisson, Guillaume,Marsura, Alain
, p. 173 - 183 (2016/05/19)
1,3,4,6-Tetrachloro (TCDGU) and 1,3,4,6-tetrabromo-3α,6α-diphenylglycolurils smooth halogen oxidizers have been exploited in a new direction as reagents for free radical substitution toward some N-halosuccinimide nonreactive bis-heterocycles. An unexpected selectivity and reactivity were observed with methyl benzenes, methyl heterocycles, and methyl-bis-heterocycles of interest. A chemometric study has been performed to optimize five independent factors of the chlorination reaction with TCDGU. The predictive model was established either for the halogenation conversion and the ratio of monochlorination.

Paragraph 0027-0034, (2016/10/07)
The invention relates to a process for synthesizing two chlorine animal pens between, which belongs to the technical field of organic chemical synthesis. The process for synthesizing two chlorine animal pens between the LED light source illuminates the under is, the m-xylene and excessive chlorine is carried out in the ionic liquid catalyst reaction, two chlorine animal pens reaction liquid obtained, then the temperature of the reaction liquid two chlorine animal pens separation, to obtain crude two chlorine animal pens, two chlorine animal pens decompress the crude product obtained after two benzyl chloride between the rectification. The prepared by the invention for the melting point of two chlorine animal pens 33-35°C, the purity of more than 99% or more; in the synthesis process of the present invention without any solvent mixins, ensuring the high purity of the product, has a short period, the cost is low, the characteristics of no harm to the environment, and is suitable for industrial production.

CHARACTERISTICS OF THE INITIATED (RADICAL) CHLORINATION OF m-XYLENE
Kosheleva, L. M.,Rozenberg, V. R.,Motsarev, G. V.
, p. 1607 - 1610 (2007/10/02)
By GLC it was established that the composition of the products from initiated chlorination of m-xylene is determined by the molar ratio of the reagents (m-xylene and chlorine).An assessment of the reactivity of the individual chlorine derivatives of m-xylene is given.
