Sequential treatment of 2,3-dichloropropene with magnesium and n-BuLi generates the operational equivalent of 1,3-dilithiopropyne, which upon treatment with aldehydes or ketones, produces the corresponding alkoxy lithium acetylide intermediates. Reaction of this alkoxide with tosyl chloride, and t-BuLi produces 1-substituted, or 1,1-disubstituted 1,3-enynes in a one-pot reaction. When this lithium acetylide intermediates, obtained by this procedure, were used to perform palladium-catalyzed cross-coupling reactions, followed by addition of thionyl chloride and pyridine, 1,4-disubstituted or 1,1,4-trisubstituted 1,3-enynes were obtained in a one-pot protocol.

Combining palladium catalyzed reactions in one-pot reactions represents an efficient and economical use of catalyst. The Suzuki-Miyaura cross-coupling has been proven to be a reaction which can be combined with other palladium catalyzed reactions in the same pot. This mini-review will highlight some of the latest examples where Suzuki-Miyaura cross-coupling reactions have been combined with other palladium catalyzed reactions in one-pot reaction. Predominantly, examples with homogeneous reaction conditions will be discussed in addition to a few examples from the authors where Pd/C have been used as a catalyst.
