Donor-Stabilized Silylenes The chemistry of donor-stabilized silylenes has developed into one of the most actively studied research areas in molecular silicon chemistry. In their Full Paper on page 296 ff., R. Tacke et al report on the synthesis and characterization of novel transition-metal silylene complexes of FeBr₂, CoBr₂, NiBr₂, ZnBr₂, and ZnCl₂ with the bis(guanidinato)silicon(II) complex [iPrNC(NiPr₂)NiPr]₂Si. These compounds represent very rare examples of carbonyl-free silylene complexes of 3d transition metals in the formal oxidation state +2.
