• W2053414900 abstract "Reaction of 2,3-bis(neopentylamino)quinoxaline ( 1 ) with n BuLi and GeCl 4 or GeCl 2 ·(dioxane) (molar ratio 1:2:1) in THF furnished highly moisture-sensitive Ge(IV) and Ge(II) heterocycles 2a and 3a , respectively. The quinoxaline-annulated N -heterocyclic germylene (quinNHGe) 3a is stable only in the presence of Li(THF) x and exhibits electrophilic properties associated with the strongly electron-withdrawing annulation. Coordination of chloride at Ge(II) and of Li + at nitrogen is assumed, as found in crystals of a bis(quinoxaline)-annulated eight-membered NHGe LiCl adduct. Addition of dineopentyl-benzimidazol-2-ylidene (bnNHC) provides a labile bnNHC-quinNHGe adduct 4 as indicated by strong downfield coordination shift of the NMR signal for the carbene donor atom. Attempts to grow single crystals led to decomposition and protonation of the carbene forming the bis(benzimidazolium) salt 5 with Li 2 ( THF ) 2 Cl 4 2 - anion. Introduction of 2-methoxyethyl or 2-dimethylaminoethyl side arms as chelating functional groups into the diaminoquinoxalines 6 and 7 and subsequent reaction with 2 n BuLi/GeCl 2 ·(dioxane) did not markedly stabilize the resulting donor-substituted quinNHGe 8 and 9 . Related silicon ( 2b ) and tin heterocycles ( 3c ) were synthesised for comparison. The quinoxaline-annulated N -heterocyclic stannylene 3c exhibits an extreme 119 Sn upfield shift compared to other N -heterocyclic stannylenes, suggesting higher coordination at tin." @default.
