Synthesis and coordination ability of a partially silicon based crown ether

Chem Commun (Camb). 2016 Nov 3;52(90):13265-13268. doi: 10.1039/c6cc07520g.

Abstract

The first hybrid crown ether with two adjacent disilane fragments was synthesized through reaction of O(Si2Me4Cl)2 (3) with O(C2H4OH)2. By means of DFT calculations, the complexation ability of 1,2,4,5-tetrasila[12]crown-4 (7) towards Li+ was determined to be considerably higher compared to [12]crown-4.
