The combination of norbornenyl-tagged (Nb-tagged) silica particles and functionalized Nb-tagged monomers for the generation of hybrid Si-ROMP reagents and scavengers is reported. Specifically Si-ROMP-derived bis-acid chloride, dichlorotriazine, and triphenylphosphine scavenger/reagents have been grafted from the surface of silica particles utilizing surface-initiated, ring-opening metathesis polymerization (ROMP). These hybrid polymeric materials combine the physical properties of current immobilized silica reagents and represent a key advancement in load by merging the inherent tunable properties of the ROMP-derived oligomers with silica supports for application in a parallel synthesis.

esters and tertiary amides has been developed. 5-Hydroxymethylfurfural (HMF) was used as both substrate and CO surrogate for the first time in a carbonylation reaction, and both alkyl and aryl iodides were tolerated well to afford the desired furfuryl esters in moderate to good yields. In addition, furfural was also utilized as a CO source for the synthesis of tertiary amides. A variety of tertiary amides
