| | 1-PENTYNE Usage And Synthesis |
| Chemical Properties | Clear colorless to pale yellow liquid | | Uses | 1-Pentyne has been used in preparation of:
- lithium acetylides, required for asymmetric synthesis of α,α-dibranched propargyl sulfinamides
- 7-hydroxy-10-methoxy-3H-naphtho[2.1-b]pyrans
| | Uses | 1-Pentyne has been used in preparation of:lithium acetylides, required for asymmetric synthesis of α,α-dibranched propargyl sulfinamides. It is also used to synthesize 7-hydroxy-10-methoxy-3H-naphtho[2.1-b]pyrans. | | General Description | Selective and non-selective hydrogenation of 1-pentyne catalyzed by silica-supported palladium has been studied by in situ X-ray absorption spectroscopy. | | Safety Profile | Dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also ACETYLENE COMPOUNDS |
