A simple method for preparing some cyclopropylcarbinyl compounds

Access to carbon–carbon bonds

“…Further synthetic applications of 1,3-deoxystannylation have already been mentioned (see 9.3.3, under Miscellaneous a-heterosubstituted organolithiums, and 9.6) and this type of reaction has been successfully extended to other γ-heterosubstituted systems 373 ' 374 ' [633][634][635][636][637][638] . However, the more interesting improvements have been provided by electrophilic addition-elimination sequences which lead to cyclopropylcarbinyl halides 633 ' 634 (Scheme 10.203 Tributyltin derivatives are more suitable than the trimethyl-or triphenyltin homologues in these reactions because there is little contamination due to the cleavage of butyl groups.…”
