Diels alder reaction limiting reagent
WebThe Diels-Alder reaction of Fischer carbene complexes can also be extended to acetylenic complexes. The reaction of complex 97 with 2,3-dimethylbutadiene gives the cycloadduct 99 in 89 % yield at 50 o C in 4 hours [ 2]. This is an -unsaturated complex, which should be useful in the benzannulation reaction. WebThe Diels‐Alder reaction is favored by the presence of electron‐withdrawing groups on the diene as well as the electron‐releasing groups on the dienophile, which is a group or bond that is attracted to a diene. ... The Limiting reagent in this Cycloaddition reaction is generally maleic anhydride, hence,
