In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called An Alternative Route to Complex Allenes or Cyclooctatrienes via a Suzuki Cyclocarbopalladation Cascade, published in 2022-01-19, which mentions a compound: 60748-47-2, mainly applied to dimethyldioxaspirodecene alkynyl bromide boronic ester palladium catalyat Suzuki cyclization; allene diastereoselective regioselective preparation; boronic ester dimethyldioxaspirodecene vinyl bromide palladium catalyat Suzuki cyclization; cyclooctatriene diastereoselective regioselective preparation; 4-exo-dig; allenes; cascade reactions; cyclocarbopalladation; cyclooctatrienes, Recommanded Product: PD2DBA3.
The 4-exo-dig cyclocarbopalladation of vinyl bromides substituted with a triple or double bond resulted in impressive cascade reactions leading to different compounds under Suzuki cross-coupling conditions upon a slight modification of the starting material. When the starting compound carries a triple bond, a single cascade occurs providing a structure containing an allene, a tetrasubstituted cyclopropane, and a cyclobutene with complete stereoselectivity. When the related starting material possessing a double bond is reacted under the same conditions in the presence of various vinyl boronic esters or acids, an efficient 8π-electrocyclization provided tricyclic systems comprised of a cyclobutene unit, as well as a cyclooctatriene. Five carbons of the latter was selectively decorated with different substituents depending on the choice of the starting material and the boronic coupling partner.
In some applications, this compound(60748-47-2)Recommanded Product: PD2DBA3 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
