摘要：
1,3,5-Trialkyl-1H-pyrazole-4-carbaldehydes reacted with 2,2′-oxydiethanethiol in the presence of chloro(trimethyl)silane as dehydrating agent at room temperature to give 4-(1,4,6-oxadithiocan-5-yl)-1H-pyrazole hydrochlorides which were converted into the corresponding free bases by treatment with 5% aqueous ammonia.
