Abstract

The dehydration of d-niethyl-2, l-pcntariediol was reported by Kyriakides' to yield 4-methyl-1, 3-pentadiene and an unsaturated alcohol distilling in the neighborhood of 130" to which was assigned the structure of 4-methyl-3-penten-2-01.'The work of subsequent investigators revealed that the hydrocarbon product is a mixture of%-methyl-1, 3-pentadiene and 4-methyl- l, 3-pentadiene, with the former predominating, 2 and that the true structure of the alcohol ...
