Similarly, lithium aluminum hydride gives different products. / -Naphthyl p-toluenesulfonate affords p-thiocresol and ) -naphthol, and phenyl meth-anesulfonate gives methyl mercaptan and phenol. On the other hand, propyl p-toluenesulfonate yields />-toluenesulfonic acid and propane, and cetyl meth-anesulfonate and cetyl p-toluenesulfonate give hexadecane in 92% and 96% yields, respectively [680]. 

Butyl methacrylate, lauryl methacrylate, and cetyl methacrylate were combined with maleic anhydride, lauryl mercaptan, and process oil and then charged into a 2-liter reaction vessel equipped with two mixing impellers rotated at 300 rpm during the reaction. The mixture was preheated to 85°C and then treated with 2,2 -azoisobutyronitrile and heated for 4 hours at 85°C followed by 1 hour at 100°C. In some cases additional oil was added to make the product more easily pourable. Unreacted maleic anhydride and other low-molecular-weight products were removed by heating the reaction mass to 120°C while applying a vacuum. Reaction scoping results are provided in Table 1. 

AIBN = 2,2 -Azoisobutyronitrile, BMA = butyl methacrylate, CMA = cetyl methacrylate, LMA = lauryl methacrylate, LSI I = lauryl mercaptan, and MA = maleic anhydride. 

The following mercaptans are prepared by the same procedure in the yields indicated isobutyl, 56% n-octyl, 73% n-dodecyl, 77% cetyl, 64% /J-phenylethyl, 70% sec-butyl, 64% hexamethylene, 63% and decamethylene, 48%. Double the above molar amounts of hydrobromic acid and thiourea are used in the preparation of hexamethylene and decamethylene mercaptan. 

DCTAB is cetyl trimethyl ammonium bromide. f ra-HM is ra-heptyl mercaptan.
