Application

1-Methyl-2-propenylmagnesium chloride is a Grignard type allylating reagent that can be used for the preparation of corresponding homoallylic alcohols by reacting with various aldehydes. It can also be utilized in the synthesis of 3,4-dihydro-4-(1-methyl-2-propen-1-yl)-2(1H)-pyrimidinethione derivatives by treating with 2-mercaptopyrimidine.
