ds-l,2-Bis(diisopropylamino-trimethyltin-boryl)hex-3-ene, rra«s-l,2-Bis(diisopropylamino-trimethylthin-boryl)etheneTrimethyltinlithium reacts with z-l,2-bis(diisopropylamino-chloro-boryl)ethene deriva tives 4a (R = Et) and 4b (R = H) to give the ds-l,2-bis(diisopropylamino-trimethyltin-boryl)-hexene-3 (2a) and, surprisingly, the frarts-l,2-bis(diisopropylamino-trimethyltin-boryl)-ethene (5 b) respectively. The constitution of 2 a and 5 b is derived from spectroscopic data, and confirmed by X-ray structure analyses. The formation of the trans-product 5 b probably occurs via a radial intermediate.
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.
