A novel magnetically recoverable organic hydride compound was successfully constructed by using silica-coated magnetic nanoparticles as a support. An as-prepared magnetic organic hydride compound, BNAH (1-benzyl-1,4-dihydronicotinamide), showed efficient activity in the catalytic reduction of α,β-epoxy ketones. After reaction, the magnetic nanoparticle-supported BNAH can be separated by simple magnetic separation which made the separation of the product easier.

Baeyer-Villiger Oxidation of Cyclobutanones with 10-Methylacridinium as an Efficient Organocatalyst. -A metal-free and convenient approach to substituted lactones under conditions A) or B) affords the target compounds with high yields. In most cases, slightly higher yields are observed under conditions A). -(XU*, H.-J.; ZHU, F.-F.; SHEN, Y.-Y.; WAN, X.; FENG, Y.-S.; Tetrahedron 68 (2012) 22, 4145-4151, http://dx.
