31. Once the enzyme OP complex has aged it is no longer regenerated by the common, oxime reactivators. 32. Benzoin ethers, Acetophenones, Benzoyl Oximes , and Acylphosphines are some examples of cleavage-type photoinitiators. 33. Unfortunately for the indanone intermediates a method is not available for direct reduction of the imine or oxime . 34. The NiCl 2 / NaBH 4 system reduces aliphatic nitro groups, nitriles and oximes completely to amines. 35. Oximes such as obidoxime, pralidoxime and asoxime ( HI-6 ) are used to restore enzyme functionality.36. This results in full enzyme recovery and the phosphate-oxime compound is eliminated from the organism via urine. 37. A significant number of amphetamine syntheses feature a nitro, imine, oxime or other nitrogen-containing functional groups. 38. Oximes can also be obtained from reaction of nitrites such as isoamyl nitrite with compounds containing an acidic hydrogen atom.39. "' Obidoxime "'is a member of the oxime family used to treat nerve gas poisoning. 40. In one modification, d-glucose is converted to the glucose oxime by reaction with hydroxylamine and sodium methoxide.
