Investigation Of 3-Methyl-2-Penten-4-Yne-L-Ol (Cis Form), Lawrence John Ferrari

Theses

The isomerization of 3-methyl-l-penten-4-yne-3-ol into trans-3-methy-2-penten-4-yne-1-ol and an isomer assumed to be the cis form has been studied. The problem of determining whether or not the arbitrarily assumed isomer is a geometrical isomer or an ordinary isomer has been brought forward in industry in the course of a synthesis of Vitamin A.

Qualitative tests on the questionable isomer were without result because of the activity that the unsaturated bonds exhibited when reagents were used to test it. AU possible isomers of the compound were reviewed and the following chemical means were employed to prove that the isomer was the geometric …
