ABSTRACT:
Processes for synthesizing tertiary alkynols by reacting carbonyl-group-containing compounds with alkynes in the presence of a basic catalyst are disclosed. Preferred products are 6,10,14-trimethyl-4-pentadecyn-6-ol compounds having the structure: ##STR1## A preferred, novel compound, 6,10,14-trimethyl-4-pentadecyne-2,6-diol, can be used in the synthesis of Vitamin E or Vitamin K.sub.1.
