Soluble polymer-supported chemistry is a technology that allows the blending of the benefits of polymer-supported synthesis and solution-phase chemistry. Herein, we describe our recent efforts in this area targeted at exploring the scope of poly(ethylene glycol) (PEG) as the matrix. Specifically we describe the use of PEG as a support for triphenyl phosphine and for the Stille reaction.

This paper considers the chemistry in a protoplanetary accretion disk during the viscous stage. The model calculation extends our previous work by including in the chemical reaction network the ionisation processes due to cosmic rays and especially the ionisation due to the extinct radio-nuclides 26Al and 60Fe which are known to have been present at the time of formation of our own solar system...

The merging of site-specific incorporation of small bioorthogonal functional groups into proteins via amber codon suppression with bioorthogonal chemistry has created exciting opportunities to extend the power of organic reactions to living systems. Here we show that a new alkyne amino acid can be site-selectively incorporated into mammalian proteins via a known orthogonal pyrrolysyl-tRNA synth...

The functionalization of carbon based nanomaterials could have applications in atmospheric chemistry and contaminants removal. In this work, a quantum chemistry and computational kinetics study has been performed on the OH radical addition to ethylene previously adsorbed on a model surface of graphene. Rate constants are calculated and compared with the ethylene + OH gas phase reaction, for whi...

Reaction of imidazolylidene-derived enetetramine 2 with aliphatic iodides and bromides (and with aryl iodides bearing alkene-containing side-chains in the ortho-position) leads to formation of aliphatic aldehydes through an unprecedented extrusion of a one-carbon unit from the enetetramine. An intermediate 2-alkylimidazoline 24 is proposed, where the alkyl group derives from the substrate; this...
