用途と製造

General Manufacturing Information1-Pentyne: ACTIVE

応用分野

使用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.

一般的な説明Selective and non-selective hydrogenation of 1-pentyne catalyzed by silica-supported palladium has been studied by in situ X-ray absorption spectroscopy.
