An efficient and convenient KF/Al2O3 mediated synthesis of nitriles from aldehydes

KF/Al₂O₃ brings about a facile one-pot and economical conversion of various aryl and alkyl aldehydes into the corresponding nitriles in high yields by reaction with hydroxylamine hydrochloride.     

KF/Al_2O_3催化下4-芳基-9,10-二氢萘并[2,1-b]-4H-吡喃衍生物的合成

在KF/Al2O3催化下,α,β-不饱和腈或α,β-不饱和羧酸酯和7-甲氧基-1,2,3,4-四氢-2-萘酮反应,生成了一系列4-芳基-9,10-二氢萘并[2,1-b]-4H-吡喃衍生物.产物的结构通过红外光谱和核磁共振氢谱进行表征,并通过X单晶衍射分析进一步证实产物的结构.
