The reaction of aldehydes with ethoxyethynylmagnesium bromide does not yield the expected secondary carbinols. In the case of aromatic aldehydes the reaction products are formed from two molecules of the aldehyde and one molecule of the acetylenic compound. The structures of these compounds have been established by several transformations (see reaction scheme I) and the chemistry of their formation has been studied (reaction scheme II). Aliphatic aldehydes and ethoxyethynylmagnesium bromide give products derived from three molecules of the aldehyde and one of the acetylenic compound. In this case also the structures of the different transformation products have been investigated (reaction scheme III). |
