Abstract

The reactivity of cycloolefins (cyclopentene, cycloheptene, cyclooctene, cyclononene, and cyclodecene) in a cometathesis reaction with 1-hexene performed with the use of the MoCl₅/SiO₂–SnMe₄ catalytic system was determined over a wide range of conversions at temperatures of 25 and 5°C. It was shown that the reactivity decreased with the size of a cycloolefin ring. The addition of triphenylphosphine to the reaction mixture led to a decrease in the weight of cometathesis products with respect to the homometathesis product 5-decene. A possible mechanism was proposed to explain the behaviors observed.

C 5 –C 10环烯烃在与1-己烯的置换反应中的反应性

摘要

使用MoCl ₅ / SiO ₂ -SnMe ₄催化体系，在一定温度范围内的转化率范围内，测定了环烯烃（环戊烯，环庚烯，环辛烯，环壬烯和环癸烯）与1-己烯的氧化反应中的反应活性。 25和5°C。结果表明，反应性随环烯烃环的大小而降低。相对于均复分解产物5-癸烯，向反应混合物中加入三苯基膦导致了复分解产物的重量降低。提出了一种可能的机制来解释观察到的行为。
