Sodium Borohydride Reduction

A new fluoride vacancy of tradition metal material (FV-LaF3-x nanosheets) is rationally designed and synthesized by sodium borohydride reduction at room temperature, which improves the nitrogen reduction performance due to multi-step promotion.

Sodium borohydride reduction of 3-hydroxy-7-benzyloxy-2,3,4'-trimethoxy-flavanone and of 3-hydroxy-2,3,7,4'-tetramethoxyflavanone is shown to yield mainly trans-trans-2-methoxyflavan-3,4-dials, a novel class of flavan derivatives. The 7-benzyloxy hemiacetal also gave a minor quantity of the cis-cis-2-methoxyflavan-3,4-dial and less of the corresponding 2,3-cis-flavan-3,4-trans-dial. Catalytic hydrogenation over palladium, or reduction with complex metal hydrides at room temperature or above, converted the hemiacetals into the flavonols from which they were originally prepared by oxidation with periodic acid in methanol.

Green Procedure

An efficient, sustainable and green procedure for the synthesis of selective orthorhombic iron(oxalate) capped Fe–Cu bimetallic oxide nanomaterial [Fe(ox)Fe–CuOx] was developed using a sodium borohydride reduction of iron(ii) salt in the presence of oxalic acid at room temperature followed by addition of copper sulfate in water.
