Methylamine ions, decomposition

Amide ions have been used for many years to induce proton abstraction reactions and therefore might be expected to react with the tetramethylammonium ion in a similar way. In 1935, the decomposition of tetramethylammonium amide in liquid ammonia was initially reported by Franklin 44> to give trimethylamine and methylamine but no experimental details were given. Later, Hazlehurst, Holliday, and Pass 63> repeated Franklin s experiment 44> and noted that a trace of ethylene was evolved. During later attempts to prepare solid tetramethylammonium amide, a... 

Methyl-dichloroamine, (W-dichloromethylamine) CH3NCI2, is prepared by treating methylamine with bleaching-powder. It is a liquid, insoluble in water, which possesses a characteristic, disagreeable odor. It boils without decomposition at 59°-60°. This fact is of interest as nitrogen chloride, NCI3, explodes violently when heated. The halogen is not converted into an ion when methyl-dichloramine is treated with water. 

A method developed to predict the rates of ion-molecule association reactions (Olmstead et al, 1976) was based on a quick randomization of energy in the collision complex and on treating the baekward decomposition of the collision complex by an application of the RRKM theory. The method was successfully applied to predict both the pressure dependence and the temperature dependence of the association rates of proton-bound dimers of ammonia, methylamine, and dimethylamine.
