The reaction of 1,3-dehydroadamantane with aliphaticaldehydes involves the Ca-H bond and forms hardly accessible branched 2-(1-adamantyl)alkylaldehydes in one stage in a yield of 60-78%. It is found that 2-(1-adamantyl)alkylaldehydes are prone to oligomerization. The reaction of 2-(1-adamantyl)-alkylaldehydes with 2,4-dinitrophenylhydrazine gave the corresponding hydrazones in a yield of 84-98%.
1,3-脱氢金刚烷与脂族醛的反应涉及C a -H键,并在一个阶段中形成难以接近的支链2-(1-金刚烷基)烷基醛,产率为60-78%。发现2-(1-金刚烷基)烷基醛易于低聚。2-(1-金刚烷基)-烷基醛与2,4-二硝基苯基肼的反应产生相应的,产率为84-98%。

A one-pot protocol to obtain C1-homologated aliphatic nitriles was achieved by treating aromatic and aliphaticaldehydes with the (methoxymethyl)triphenylphosphonium ylide followed by hydrolysis of the resulting methyl vinyl ethers with pTsOH (Ts = para-toluenesulfonyl) and treatment with molecular iodine and aqueous ammonia under metal cyanide free conditions. Neopentyl-type nitriles, which could
