Influence of BH₃ and alkaline cation released from the reduction agent on a tandem reduction/acylation reaction—A computational study

Abstract

ABSTRACT:When an alkaline boron hydride is used as reduction reagent two byproducts are released, BH 3 and alkaline cation, and both of them could influence the following reaction steps if a multi-step reaction is performed in tandem one-pot fashion. We report a theoretical study on the stability of possible complexes of the Lewis acids, BH 3

Crystal Structure and Spectroscopic Properties of (2-oxo-2H-chromen-3-yl)phosphonic Acid Monoethyl Ester Trihydrate

“…1,2 As a part of our systematic study on the synthesis, 3-10 spectroscopic, and structural characterization of novel coumarins, [8][9][10] their salts, and metal complexes [11][12][13][14][15][16][17][18] with potential biological activity, [1][2][3][4][5] we are presenting here the crystal structure and spectroscopic properties of novel (2-oxo-2H-chromen-3-yl)phosphonic acid monoethyl ester trihydrate, shown in Figure 1.…”
