Addition‐elimination reactions from germanium heterocycles . II. 2‐Germa‐1,3‐diazolidines (X Y NMe). The reactivity of 2‐Germa‐1,3‐diazolidines with unsaturated compounds such as heterocumulenes (CS 2 , PhNCO, PhNCS) and with carbonyl compounds (aldehydes and ketones) has been investigated. Generally the formation of mono‐ and diinsertion derivatives is observed. The elimination reactions of (Et 2 GeO) n and (Et 2 GeS) 3 from these addition derivatives lead to corresponding carbon diazolidines. The mechanism of these addition‐elimination reactions is precised. The interest of these reactions in organic synthesis is underlined.
