Carbon dioxide sorbents with propylamine groups-silica functionalized with a fractional factorial design approach.

Langmuir : the ACS journal of surfaces and colloids

Aziz B, Zhao G, Hedin N.
PMID: 21361345
Langmuir. 2011 Apr 05;27(7):3822-34. doi: 10.1021/la104629m. Epub 2011 Mar 01.

Mesoporous silica particles (Davisil) were functionalized with aminopropyltriethoxysilane (APTES) in a fractional factorial design with 19 different synthesis and uptake experiments. The number of amino groups and the uptake of CO(2) were optimized in a 2(V)(5-1) design. Most important...

Lewis base-promoted hydrosilylation of cyclic malonates: synthesis of beta-substituted aldehydes and gamma-substituted amines.

The Journal of organic chemistry

Frost CG, Hartley BC.
PMID: 19348489
J Org Chem. 2009 May 01;74(9):3599-602. doi: 10.1021/jo900390d.

The Lewis base-promoted hydrosilylation of cyclic malonates provides a convenient synthesis of beta-substituted aldehydes. No over-reduction to the primary alcohol is observed as the aldehyde functionality is protected until a subsequent hydrolysis step. The utility of the method is...

Facile synthesis of optically pure 1,2-diaryl (and 1-Alkyl-2-aryl) ethyl and propylamines.

Organic letters

García Ruano JL, Alemán J, Soriano JF.
PMID: 12605488
Org Lett. 2003 Mar 06;5(5):677-80. doi: 10.1021/ol027464h.

A concise high-yielding route to synthetically useful 1,2-diaryl (and 1-alkyl-2-aryl) ethyl and propylamines in high enantiomeric purity is described. The key step of this route is the completely stereoselective addition of lithium (R)-ortho-(p-toluenesulfinyl)benzylic carbanions to (S)-N-p-toluenesulfinylimines, which takes place...

Temperature-induced uptake of CO2 and formation of carbamates in mesocaged silica modified with n-propylamines.

Langmuir : the ACS journal of surfaces and colloids

Bacsik Z, Atluri R, Garcia-Bennett AE, Hedin N.
PMID: 20218553
Langmuir. 2010 Jun 15;26(12):10013-24. doi: 10.1021/la1001495.

Adsorption-mediated CO(2) separation can reduce the cost of carbon capture and storage. The reduction in cost requires adsorbents with high capacities for CO(2) sorption and high CO(2)-over-N(2) selectivity. Amine-modified sorbents are promising candidates for carbon capture. To investigate the...
