Double‐cross : An annulation approach to functionalized polycyclic aromatic hydrocarbons involving a palladium‐catalyzed double cross‐coupling reaction of vic ‐diborylalkenes and ‐phenanthrenes with 2,2′‐dibromobiaryls led to a variety of phenanthrenes and dibenzo[ g , p ]chrysenes, as well as [5]helicenes, dithienobenzenes, and triphenyleno[1,2‐ b :4,3‐ b ′]dithiophenes (see scheme; B pin =pinacolatoboryl).
