Dimethyl cyclopropanes can be prepared by the reaction of an ฮฑ, ฮฒ-unsaturated carbonyl compound X with two equivalents of a Wittig reagent Y. Draw a stepwise mechanism for this reaction.
Although diazomethane ( ) is often not a useful reagent for preparing cyclopropanes,other diazo compounds give good yields of more complex cyclopropanes. Draw a stepwisemechanism for the conversion of diazo compound A to B, an intermediate in the synthesis ofsirenin, the sperm attractant produced by the female gametes of the water mold Allomyces.
In addition to using and base to synthesize dihalocarbenes (Section 26.4), dichlorocarbene can be prepared by heating sodium trichloroacetate. Draw a stepwise mechanism for this reaction.
