설명
4,4-Dimethyl-2-pentyne is used in organometallic reactions for regioselectivity of its insertion into the Pd-C bond of cyclopalladated complexes. It is also used to prepare pyrimidine-dione by reacting with isocyanate in the presence of nickel/ N-heterocyclic carbene.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
