Condensation of diacetylene with carbonyl compounds in the presence of tetramethylammonium hydroxide
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19731 Tetramethylammonium hydroxide causes the condensation of carbonyl compounds in aqueous medium. 2. The methyl ethers of di- and tetraacetylenic glycols were obtained from tetramethylhexadiynediol.

Raman study on molecular motion in tetramethylammonium hydroxide pentahydrate
The Journal of Chemical Physics, 1991The Raman spectrum as well as conductivity and differential-thermal-analysis (DTA) thermogram of tetramethylammonium hydroxide pentahydrate was observed at various temperatures in order to investigate molecular motion in relation to conductivity and a phase transition.

Proton chemical shifts have been determined over a range of temperature for water, and for aqueous sodium fluoride and sodium or tetramethylammonium hydroxide solutions using Me4N+ as an internal standard. The water results agree closely with those of Hindman and confirm that the shift temperature dependence is not constant over the range 0–100 °C. The

Polyhedral Clathrate Hydrates. XI. Structure of Tetramethylammonium Hydroxide Pentahydrate
The Journal of Chemical Physics, 1966The crystal structure of tetramethylammonium hydroxide pentahydrate has been determined at 25°C by an analysis of the three-dimensional x-ray-diffraction data. The unit cell is orthorhombic with a=12.57, b=10.96, c=7.91 Å and contains four formula units.
