One-pot formation and derivatization of di- and triynes based on the Fritsch-Buttenberg-Wiechell rearrangement

(Chemical Equation Presented) A divergent, one-pot synthesis of functionalized polyynes has been developed. Beginning with the appropriately substituted dibromoolefinic precursor, a carbenoid Fritsch-Buttenberg-Wiechell (FBW) rearrangement is used to gene

A one-pot synthesis and functionalization of polyynes

A one-pot synthesis and derivatization of diynes and triynes is reported. The polyyne framework is formed from a dibromoolefin precursor based on a carbenoid rearrangement, and the resulting Li-acetylide is then trapped in situ with an electrophile to pro
