“…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.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
