4-Toluenesulfonyl chloride → HCID 53748711, compound

Participants

Reaction Steps

To a mixture of p-toluenesulfonyl chloride (22.4 g., 0.12 moles) and 50 ml. of anhydrous pyridine is added 14 g. of non-4-en-6-yn-1-ol (0.107 moles) with ice bath cooling. The mixture is stirred for 1 hour and then is stored at 0° overnight. Ice is added to the mixture which is extracted with several portions of 50:50 ether/hexane. The combined organic phase is washed with 5% HCl, water, saturated sodium bicarbonate and dried over sodium sulfate. Removal of solvent at reduced pressure and subsequent solvent removal at 0.15 mm. for one hour gives 1-tosyloxy-non-4-en-6-yne (28 g.).
