Diverse reactivity of a boraguanidinato germylene toward organic pseudohalides

Abstract

The reactions of the boraquanidinato germylene (i-Pr)₂NB(NDmp)₂Ge (1) (Dmp = 2,6-Me₂C₆H₃) with RN₃ and RNCS produced rare examples of Ge₂N and Ge₃S rings, while the treatment of 1 with RNCO led to an insertion into the N–Ge bond leading to a novel type of germylene stabilized within a six membered ring, i.e. [N(R)C(O)N(Dmp)B(N(i-Pr)₂)N(Dmp)]Ge (R = t-Bu or Ad).
