各类型醛 ,在 2 8%氨水中与 1.1当量的碘在室温下反应 5～ 6 0 min,生成相应的腈 ,除 1例因挥发性高收率为 5 7%外 ,其余 13例收率 83%～ 97%。醛在氨水中用碘直接转化为腈@赵立志 Various aldehydes were reacted with 1.1 equivalents of iodine in 28% aqueous ammonia at room temperature for 5-60 min to yield the corresponding nitrile. Except for 1 case with high volatile yield of 57%, the remaining 13 83% ~ 97%. Aldehydes in ammonia with iodine directly converted to nitrile @ Zhao Lizhi
