2,2,3-trichloropropanal

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture consisting of 16.2 gm of 2,2,3-trichloropropionaldehyde and 4.5 gm of formamide was stirred on a boiling water bath for 30 minutes. Recrystallization of the reaction product from benzene yielded 17 gm of the desired compound, m.p. 105°-109° C. Recrystallization of the reaction product from benzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 11.3 g of 2,2,3-trichloropropionaldehyde were added dropwise to 9.2 g (0.056 mol) of 1-methyl-1-(1,2,4-triazol-1-yl-acetyl)-cyclopropane in 120 ml of tetrahydrofuran and 13.6 g (0.1 mol) of potassium carbonate, the temperature increasing slightly. The reaction solution was stirred overnight at room temperature and was thereafter introduced into 500 ml of water. The resulting precipitate was filtered off under suction and recrystallized from methanol. 5.5 g (30% of theory) of 1,2,2-trichloro-3-hydroxy-4-(1,2,4-triazol-1-yl)-5-(1-methylcycloprop-1-yl)-pentan-5-one of melting point 182° to 186° C. were obtained. the temperature increasing slightly The resulting precipitate was filtered off under suction recrystallized from methanol
