Amino-derivatives of Pentaerythritol

Abstract

TETRAMINO-TETRAMETHYL-METHANE, C(CH₂NH₂)₄, was first prepared (in the form of its salts) by Govaert¹ by heating tetrabromo-pentaerythritol, C(CH₂Br)₄, with alcoholic ammonia in sealed tubes. This preparation has recently been repeated by van Alphen₂, who has isolated the free base and prepared various derivatives. The method of preparation is unsatisfactory, however, as the quantities of the tetrabromo-compound employed are limited by the use of sealed tubes, and the yield is low.
