| | 4,4-Dimethyl-2-pentyne Usage And Synthesis |
| Uses | 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. | | Synthesis Reference(s) | Tetrahedron Letters, 22, p. 2443, 1981 DOI: 10.1016/S0040-4039(01)92928-4 |
