Agarwal, C. V.; Verma, V. K.; Sarma, D. S. (Inst. Technol., Banaras Hindu Univ., Varanasi 221 005, India). Indian J. Technol., 16(12), 587-9 (English) 1978. CODEN: IJOTA8. ISSN: 0019-5669. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Benzyl chloride [100-44-7], 4-chlorobenzyl chloride [104-83-6], 1-chloro-4-nitrobenzene [100-00-5], 1-chloro-2,4--dinitrobenzene [97-00-7] and hexachloroethane [67-72-1] have been evaluated for their effectiveness as extreme pressure lubricant additives on a 4-ball lubricant testing machine. Hexachloroethane is superior to the other compds. tested.

DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 28 The triazole and imidazole derivs. I (R1 = substituted benzyl; R2= iso-Pr or tert-Bu; R3 = H or Me; Y = N or CH) are fungicides. Thus, in pot expts., 100 ppm 1-tert-butyl-2-(1,2,4-triazol-1-yl)-2-p-chlorobenzylethanol (II) [66345-53-7] controlled Puccinia recondita on wheat, Plsmopara viticola on grape, Piricularia oryzae on rice, and Erysiphe graminis on barley. II was prepd.Several reagents such as 66345-53-7 is used here. by reaction of 1,2,4-triazole [288-88-0] with bromopinacolone [5469-26-1] to give 1,2,4-triazol-1-ylpinacolone [58905-32-1], which upon reaction with p-chlorobenzyl chloride [104-83-6] yielded a-(p-chlorobenzyl)-a(1,2,4-triazol-1-yl)pinacolone [63190-87-4]. Redn. of the last compd. with NaBH4 gave I. .
