Participants

Reaction Steps

Using the procedure of Example I, 1-bromo-3-propyl-2-hexene was reacted with sodium phenyl sulfinate to form (3-propyl-2-hexenyl)-phenyl sulfone which was then reacted with ethyl β,β-dimethyl-acrylate to form ethyl dl-trans 3,3-dimethyl-2-(2'-propyl-1'-pentenyl)-cyclopropanecarboxylate having a boiling point of 80° C. at 0.06 mm Hg and a refractive index nD22 =1.464. The said ethyl ester was hydrolyzed under alkaline conditions to form dl-trans 3,3-dimethyl-2-(2'-propyl-1'-pentenyl)-cyclopropane carboxylic acid having a boiling point of 116° C. at 0.05 mm Hg and a refractive index nD22 =1.4755 which was then reacted with thionyl chloride to obtain dl-trans 3,3-dimethyl-2-(2'-propyl-1'-pentenyl)-cyclopropanecarboxylic acid chloride having a boiling point of 75° C. at 0.04 mm Hg and a refractive index nD24 =1.4795.
