Summary

  1. 1.

    A method was developed for the preparation of mixed diacetylenic organosilicon glycols. Five such glycols were prepared for the first time: 4,4′-(methylphenylsilylene)-, 4,4′-(ethylphenylsilylene)-, 4,4′-(diphenylsilylene)-, 4,4′-(diethylsilylene)-, and 4,4′-(methylnaphthylsilylene)-bis[2-methyl-3-butyn-2-ol).

  2. 2.

    The presence of hydroxy groups in the mixed organosilicon glycols was proved by the synthesis of the corresponding acetyl derivatives (VI).

  3. 3.

    4,4′-(Methylphenylsilylene)bis[2-methyl-3-butyn-2-ol] diacetic ester and 4,4′-(methylphenylsilylene)-bis[2-methyl-2-butanol] were prepared and characterized for the first time.

  4. 4.

    The presence of two triple bonds in the glycols was proved by quantitative catalytic hydrogenation to the corresponding saturated compounds.
