| Hazard Information | Back Directory | [Uses]
Used as allylic electrophile which allows efficient control of the chemo-, regio-, and stereoselectivity in the C-C
coupling process by reaction with organocopper reagents. | [Synthesis]
2-allyloxybenzothiazoles are prepared by reaction of potassium allyloxides with 2- chlorobenzothiazole in dry ether at rt. 2-Allylthiobenzothiazoles are prepared by reaction of allylic alcohols with 2,2′-dithiobis(benzothiazole) and triphenylphosphine or with benzothiazole-2-thiol, diethyl azodicarboxylate, and triphenylphosphine in dry toluene at rt. |
