Xiong, Yu-qing published the artcileSynthesis process of diethyl(o-cyanobenzyl)phosphonate, Safety of 2-(Chloromethyl)benzonitrile, the publication is Yingyong Huagong (2014), 43(11), 2012-2013, 2018, database is CAplus.
Aiming at pollution from o-cyanobenzyl chloride and benzene, a green synthesis process was provided by using o-cyanotoluene as starting mol., after photochlorination, o-cyanobenzyl chloride directly reacted with a slight excess of tri-Et phosphate by esterification reaction without adding other organic solvents. The results showed that the optimal technol. condition was chlorination at 140°C, 1.0 of chlorination degree, using incandescent light bulb, esterification at 155°C for 4 h. The critical factor was controlling chlorination degree under 1.0, combination of photochlorination and esterification, in order to reduce pollution to environment.
Yingyong Huagong published new progress about 612-13-5. 612-13-5 belongs to nitriles-buliding-blocks, auxiliary class Organic Pigment, name is 2-(Chloromethyl)benzonitrile, and the molecular formula is C3H5F3O, Safety of 2-(Chloromethyl)benzonitrile.
