cyclopropanecarbonyl cyclopropanecarboxylate

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

Procedure: This was prepared from cyclopropanecarboxylic acid (Aldrich) and cyclopropanecarboxylic acid chloride (Aldrich) by the method given (Example IV) for the preparation of the cyclobutyl analogue and purified by vacuum distillation; bp 95°-100° C. at 6 torr (lit.: Castro and Dormoy, Bull. Soc. Chem. Fr. 8, 3034 (1971) bp 102°-104° C. at 8 torr); IR anhydride C=O stretch absorptions at 5.53 and 5.74μ. purified by vacuum distillation
