The 1,1-Carboboration of Bis(alkynyl)phosphanes as a Route to Phosphole Compounds

The 1,1-Carboboration of Bis(alkynyl)phosphanes as a Route to Phosphole Compounds

Neat and tidy: B(C6F5)3 efficiently converts a series of bis(alkynyl)phosphanes into highly substituted 3‐borylphospholes through a twofold 1,1‐carboboration reaction sequence. The boron substituted phospholes were also used as substrates in Suzuki–Miyaura type cross‐coupling reactions (see scheme)....
