An iminosilylene (LSiCp ) with a bulky bis 2,6-diisopropylphenyl)imidazolin-2-iminato substituent and an electron-donating Cp (Cp = MesCs) group is described (1). The iminosilylene LSiCp is accessible in reasonable yield of 57% (method 1) through the salt metathesis reaction of Jutzi s silyliumylidene cation (2) with the imidazolin-2-iminato lithium salt LIT L = bis 2,6-diisopropylphenyl)imidazolin-2-iminato. An alternate approach is the reduction of the dibromosilane precursor, however, the yield is low in this reaction (Scheme 6.4.2.1).
