“…N- [[[(2,2-Diphenylcyclopropyl)methoxy]oxalyl]oxy]pyridine-2-thione (1c). Following the general procedure, the acid chloride from (2,2-diphenylcyclopropyl)methanol (0.15 g, 0.48 mmol) was allowed to react with the sodium salt of N -hydroxypyridine-2-thione (0.078 g, 0.52 mmol) to give 1c in 88% yield. 1 H NMR (CDCl 3 ): δ 1.42 (dd, J = 5.5, 9.3 Hz, 1H), 1.52 (t, J = 5.5 Hz, 1H), 2.05−2.21 (m, 1H), 4.05 (dd, J = 8.1, 11.1 Hz, 1H), 4.25 (dd, J = 6.6, 11.1 Hz, 2H), 7.10−7.50 (m, 12H), 7.86 (dd, J = 2.1, 8.4 Hz, 1H), 8.33 (dd, J = 1.5, 6.9 Hz, 1H).…”

“…Following the general procedure, the acid chloride from (2,2-diphenylcyclopropyl)methanol 36 (0.15 g, 0.48 mmol) was allowed to react with the sodium salt of N-hydroxypyridine-2-thione (0.078 g, 0.52 mmol) to give 1c in 88% yield. 1 36 (0.52 g, 2.3 mmol) in 10 mL of CH2Cl2 was added a 1.92 M solution of phosgene in toluene (1.8 mL, 3.5 mmol) at room temperature. The mixture was stirred at room temperature for 48 h, and solvent and excess phosgene and toluene were removed by distillation under a water aspirator vacuum followed by high vacuum to yield 0.67 g (2.3 mmol, 101%) of (2,2-diphenylcyclopropyl)methoxy chloroformate.…”

“…In a 500-mL, three-necked flask fitted with a mechanical stirrer were placed 25.0 g (135 mmol) of m-bromobenzaldehyde, 16.2 g (135 mmol) of acetophenone, and 100 mL of 95% ethanol. The stirrer was started and the mixture brought to 35 °C by means of a water bath. To the mixture was added a solution of 10 g of sodium hydroxide in 50 mL of water.…”
