CAS 16400-32-1: 1-Bromo-2-pentyne

1-Bromo-2-Pentyne

1-Bromo-2-pentyne acts as a reagent for organic and organometallic compounds. It is also employed in the preparation of stereochemically restricted lactone-type analogs of jasmonic acids, 5-oxa-7-epi-jasmonic acid and 5-oxa-jasmonic acid. Further, it is used to prepare of 4,7-decadienal, 4,7-tridecadienal, 5,8-tetradecadienal and 6,9-dodecadienal synthesis. In addition to this, it plays an important role for the synthesis of 5-ethyl-4-methylene-6-phenyl-3a,4,7,7a-tetrahydroisobenzofuran-1,3-dione. 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.

1-Bromopent-2-yne is a volatile oil that has been used as an analog for the tropane alkaloid scopolamine. It is a fatty acid with hydroxy, halide, and unsaturated groups. 1-Bromopent-2-yne reacts with chloride to form a phosphonium salt in a reaction mechanism that is catalyzed by acidic conditions. This reaction leads to the formation of an enolate, which can then be used in catalytic asymmetric synthesis.
