Xanthates, Chugaev elimination secondary alcohols

The behaviour of tertiary alcohols in the Chugaev elimination mirrors that of primary and secondary systems however, relatively few examples have been reported. The 5-methyl xanthate of dimethylcyclopropylcarbinol 30 was pyrolyzed to give the olefin in 24%... [Pg.339]

The Chugaev elimination of tertiary alcohols is improved by use of the potassium xanthate rather than the 5-methyl xanthate this method cannot be extended to primary or secondary alcohols. Secondary alcohols are dehydrated on heating in hexamethylphosphoramide the transition state (209) is proposed. [Pg.165]
