study explores a new mode of contortion in perylenediimides where the molecule is bent, like a bow, along its long axis. These bowed PDIs were synthesized through a facile fourfold Suzuki macrocyclization with aromatic linkers and a tetraborylated perylenediimide that introduces strain and results in a bowed structure. By altering the strings of the bow, the degree of bending can be controlled from
Nickel(II)-Magnesium-Catalyzed Cross-Coupling of 1,1-Dibromo-1-alkenes with Diphenylphosphine Oxide: One-Pot Synthesis of (<i>E</i>)-1-Alkenylphosphine Oxides or Bisphosphine Oxides
A novel nickel(II)‐magnesium‐mediated cross‐coupling of diphenylphosphine oxide with a variety of 1,1‐dibromo‐1‐alkenes has been developed, which provides a powerful and general methodology for the stereoselectivesynthesis of various (E)‐1‐alkenylphosphine oxides or bisphosphine oxides, with operational simplicity of the procedure, good to high yields and broad substrate applicability. Mechanistic
