β¦ Synopsis
a b s t r a c t Solutions of heterocycles having an allyl sulfide unit and simple alkenes in 50% t-BuOH/H 2 O undergo reversible olefin metathesis reactions with the second generation Hoveyda-Grubbs catalyst. The choice of functional groups is limited by competitive chelation of some heterocycles with the catalyst, and other stereoelectronic effects.
