Preparation of cyclic alkenylmagnesium reagents via an iodine/magnesium exchange.
نویسندگان
چکیده
The reaction of various cyclic alkenyl iodides with i-PrMgCl.LiCl produces the corresponding alkenylmagnesium reagents under mild conditions. After reaction with various electrophiles, like allylic halides, disulfides, aldehydes and acid chlorides, the expected products are obtained in 53-91% yield. Remarkably, the mild conditions of the I/Mg-exchange tolerate the presence of sensitive diene functionalities.

An efficient generation method and remarkable reactivities of 3-triflyloxybenzyne.
3-Triflyloxybenzyne was generated via an iodine-magnesium exchange reaction of 1,3-bis(triflyloxy)-2-iodobenzene using the trimethylsilylmethyl Grignard reagent. Various arynophiles and nucleophiles reacted regioselectively with 3-triflyoxybenzyne to afford cycloadducts and unique aryl triflones, which were provided via thia-Fries rearrangement.

Stereoselective synthesis of 5-7 membered cyclic ethers was achieved by deiodonative ring-enlargement of cyclic ethers having an iodoalkyl substituent. The reaction took place readily under mild conditions using hypervalent iodine compounds and an acetoxy or a trifluoroacetoxy group was introduced into the rings depending on the hypervalent iodine reagent employed. The use of hexafluoroisopropa...
