WebChemInform Abstract: Reductive, Selective Deoxygenation of Acylbenzo [b]furans, Aromatic Aldehydes and Ketones with NaBH3CN/TMSCl. Article Sep 1998 Vernon G.S. Box … WebTMSCl works as an acid catalyst precursor for selective esterification of L-aspartic and L-glutamic acids in the presence of primary, secondary and tertiary alcohols. Although excess TMSCl was required for the completion of esterification, the resulting alkyl TMS ether could be azeotropically removed by simple evaporation with alcohol.

WebIf you want to do a reductive amination you should use NaBH3CN (sodium cyanoborohydride), not NaBH (CN)3 (sodium tricyanoborohydride). Minor amounts should be perfectly fine, especially in a fumehood. Yes it does form HCN and H2, since HCN is pretty soluble in protic solvents I assume the gas is mostly H2.

WebSodium cyanoborohydride (NaBH3CN) is a mild reducing agent that is commonly used in reductive aminations. The presence of the electron-withdrawing cyano (CN) group makes it less reactive than sodium borohydride ( NaBH4 ). This reduced reactivity allows NaBH3CN to be employed at neutral or slightly acidic conditions for the selective reduction ... WebJul 22, 2024 · A mild process using a combination of TMSCl and NaI in acetonitrile is used to regenerate carbonyl compounds from a variety of dithiane and dithiolane derivatives. This easy to handle and inexpensive protocol is also efficient to deprotect oxygenated and mixed acetals as 1,3-dioxanes, 1,3-dioxolanes and 1,3-oxathianes quantitatively.
