Suzuki coupling of cyclopropylboronic acid with aryl halides catalyzed by a palladium-tetraphosphine complex
The tetraphosphine all-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)- cyclopentane (Tedicyp) in combination with [Pd(C3H 5)Cl]2 affords a very efficient catalyst for the coupling of cyclopropylboronic acid with aryl bromides and aryl chlorides. Higher reactions rates were observed with aryl bromides than with aryl chlorides; however, even in the presence of 1-0.4% of catalyst, a few aryl chlorides gave the coupling products in good yields. A wide variety of substituents such as alkyl, methoxy, trifluoromethyl, acetyl, benzoyl, formyl, carboxylate, nitro, and nitrile on the aryl halides are tolerated. The coupling reaction of sterically very congested aryl bromides such as bromomesitylene or 2,4,6-triisopropylbromobenzene also proceeds in good yields. Copyright Taylor & Francis LLC.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C9H6BrN, you can also check out more blogs about1532-97-4
