Abstract
1. 2-Methyl-1,3-dioxolan quantitatively precipitates magnesium bromide and vinylethynylmagnesium bromide (VEMB) from the etherate of the corresponding Iotsich complex, bis-(vinylethynyl)-magnesium remaining in the solution. The composition of the mixture of insoluble dioxolanates has been studied. 2. The reaction of 1,3-dioxolans with VEMB is considered as a coordinate nucleophilic exchange taking place by a cyclic mechanism with the participation of an “acetal-magnesium bromide complex,” on the one hand, and bis-(vinylethynyl)-magnesium on the other hand.
