The present microreview summarizes our progress over the last few years in defining regioselective reductive cross-coupling reactions of unsymmetrical alkynes with terminal-and internal alkynes, aldehydes, and imines. We begin with a brief historical perspective of metalmediated reductive dimerization reactions of aromatic alkynes and discuss the challenges associated with "crossed" versions of this mode of reactivity. Next, a collection of available methods that allow for regioselectivedoi:10.1002/ejoc.200901094 pmid:24634606 pmcid:PMC3951371 fatcat:k2cvgmtbobd7xavodum7sl6vvm
