摘要

A general thermolysis reaction for the transformation of Group 1 TMP compounds (LiTMP, NaTMP, KTMP) to 1-aza-allylic TTHP derivatives is reported. TMEDA accelerates the reaction and produces the crystalline complexes [(TMEDA) LiTTHP] and [(TMEDA.NaTTHP)(2)]. Methane elimination during the transformational process was confirmed via TVA coupled to MS.
