Distillable ionic liquids : reversible amide O alkylation
Put it in reverse: The recycling of ionic liquids (ILs) by distillation of the regenerated volatile precursors was demonstrated to be feasible by using low-cost amide-cation-derived aprotic ionic liquids prepared from ...
A silyliumylidene cation stabilized by an amidinate ligand and 4-dimethylaminopyridine
The synthesis and reactivity of a silyliumylidene cation stabilized by an amidinate ligand and 4-dimethylaminopyridine (DMAP) are described. The reaction of the amidinate silicon(I) dimer [LSi:]2 (1; L=PhC(NtBu)2) with one ...
A base-stabilized 2-silaallene
The reaction of [CH2(PPh2S)2] (1) with 2 equiv of MeLi in Et2O followed by addition of 0.5 equiv of SiCl4 afforded the base-stabilized 2-silaallene [(PPh2S)2CSiC(PPh2S)2] (2). It has been characterized by X-ray crystallography, ...
A base-stabilized lead(I) dimer and an aromatic plumbylidenide anion
The aromatic low-valent lead analogue of an indenyl anion (see scheme; 1) undergoes oxidation with SnCl2 to form the base-stabilized lead(I) dimer 2. Reduction of 2 with lithium regenerates 1. These compounds were characterized ...
