| It was shown that the cobalt(I)-catalyzed Diels–Alder reaction of propargylic phosphonium salts and alkyne-functionalized phosphonium salts with 1,3-dienes led to dihydroaromatic phosphonium salt intermediates that were directly used in a one-pot Wittig-type olefination reaction with aldehydes. Subsequent oxidation led to styrene- and stilbene-type products with the formation of three new carbon–carbon bonds. The reaction gives predominantly the E-configured products. |

It was shown that the cobalt(I)-catalyzed Diels–Alder reaction of propargylic phosphonium salts and alkyne-functionalized phosphonium salts with 1,3-dienes led to dihydroaromatic phosphonium salt intermediates that were directly used in a one-pot Wittig-type olefination reaction with aldehydes. Subsequent oxidation led to styrene- and stilbene-type products with the formation of three new carbon–carbon bonds. The reaction gives predominantly the E-configured products. 钴催化的炔丙基膦盐或炔功能化的膦盐与1,3-二烯进行Diels–Alder反应生成氢化芳族盐中间产物,这些中间产物可直接和乙醛进行Wittig烯化反应。随后的氧化通过形成三种新的碳碳键得到苯乙烯和均二苯代乙烯类产物。该反应的产物绝大多数是E型(式)的。 |
