A New Monomeric Saturated N-Heterocyclic Silylene as a Racemic Mixture

A new stable silylene, rac-N,N‘-di-tert-butylethylene-4,5-dimethyl-1,3-diaza-2-silacyclopentan-2-ylide, has been made by reaction of the corresponding dibromide with KC8. Unlike the analogous silylene lacking the two methyl groups, which tetramerizes in concentrated solution or as a solid, the new s...

Summary:A new stable silylene, rac-N,N‘-di-tert-butylethylene-4,5-dimethyl-1,3-diaza-2-silacyclopentan-2-ylide, has been made by reaction of the corresponding dibromide with KC8. Unlike the analogous silylene lacking the two methyl groups, which tetramerizes in concentrated solution or as a solid, the new silylene shows no tendency to oligomerize; instead, it persists as a stable colorless liquid.
