Category: chiral-phosphine-ligands. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(Bromomethyl)-2-iodobenzene, is researched, Molecular C7H6BrI, CAS is 40400-13-3, about Selenenate Anions (PhSeO-) as Organocatalyst: Synthesis of trans-Stilbenes and a PPV Derivative. Author is Zheng, Zhipeng; Trofymchuk, Oleksandra S.; Kurogi, Takashi; Varela, Elena; Mindiola, Daniel J.; Walsh, Patrick J..
The selenenate anion (RSeO-) is introduced as an active organocatalyst for the dehydrohalogenation coupling of benzyl halides to form trans-stilbenes. It is shown that RSeO- is a more reactive catalyst than the previously reported sulfur analogs (sulfenate anion, RSO-) and selenolate anions (RSe-) in the aforementioned reaction. This catalytic system was also applied to the benzylic-chloromethyl-coupling polymerization (BCCP) of a bis-chloromethyl arene to form ppv (poly(p-phenylene vinylene))-type polymers with high yields, Mn (average mol. weight) up to 13,000 and D (dispersity) of 1.15.
