Participants

Reaction Steps

2-Hydroxyimino-2-phenylacetic acid (syn isomer) (4.13 g, 25.0 mmole), triethylamine (8.7 ml, 62.5 mmole) and triphenylchloromethane (10.40 g, 37.5 mmole) were reacted together as described in Preparation 2(a) to give triethylammonium 2-triphenylmethoxyimino-2-phenylacetate (syn isomer) as a white solid (10.625 g, 21 mmole, 84%) m.p. 166 to 175 (dec), λmax 260 nm, inflexions at 264 and 292 nm (ε15,000; 14,400 and 2,300 respectively).
