J. Laduranty et L. Miginiac, ALLYL MAGNESIUM COMPOUNDS AS SYMMETRICAL AND ASYMMETRIC FUNCTIONALIZATION AGENTS IN POSITIONS 2 AND 5 OF 1,3,4-THIADIAZOLE, Journal of organometallic chemistry, 464(1), 1994, pp. 1-9
Allylic Grignard reagents easily react through addition and eliminatio
n, with the two methylthio groups of 2,5-bis(methylthio)-1,3,4-thiadia
zole, and with the one methylthio group of 5-methylthio-1,3,4-thiadiaz
ol-2(3H)-thione, to lead to symmetrical or unsymmetrical disubstituted
derivatives of 1,3,4-thiadiazole.
