Abstract
The present disclosure provides methods for conducting chemical reactions and for conducting a multi-step chemical reactions using swellable organically modified silica (SOMS) as nanoreactors.
Claims21
A method for conducting a chemical reaction comprising:
- (i) combining reactants, solvent, and swellable organically modified silica (SOMS) to create a reaction mixture;
- (ii) conducting a first reaction cycle by evaporating the solvent from the SOMS;
- (iii) optionally conducting an additional reaction cycle by
- (a) reintroducing solvent to the SOMS;
- and then
- (b) evaporating the solvent from the SOMS;
- (iv) optionally repeating step (iii) one or more times;
- (v) washing the SOMS with solvent to recover the product in solution;
- and
- (vi) evaporating the solvent from the product solution of step (v) to isolate the product.

A method for conducting a multi-step chemical reaction comprising:
- (i) conducting a first reaction by
- (a) combining reactants, solvent, and swellable organically modified silica (SOMS) to create a reaction mixture;
- (b) conducting a first reaction cycle for the first reaction by evaporating the solvent from the SOMS;
- (c) optionally conducting an additional reaction cycle for the first reaction by
- (I) reintroducing solvent to the SOMS;
- and then
- (II) evaporating the solvent from the SOMS;
- (d) optionally repeating step (c) one or more times;
- (ii) conducting a subsequent reaction by
- (a) introducing solvent and one or more additional reactants to the SOMS;
- (b) conducting a first reaction cycle for the subsequent reaction by evaporating the solvent from the SOMS;
- (c) optionally conducting an additional reaction cycle for the subsequent reaction by
- (I) reintroducing solvent to the SOMS;
- and then
- (II) evaporating the solvent from the SOMS;
- (d) optionally repeating step (c) one or more times;
- (iii) optionally repeating step (ii) one or more times;
- (iv) washing the SOMS with solvent to recover the final product in solution;
- and
- (v) evaporating the solvent from the final product solution of step (iv) to isolate the final product.
