Methaneselenol is the organoselenium compound with the formula CH
3SeH. It is the simplest selenol. A colorless gas, it is notorious for its foul odor.
It is prepared by reaction of methyl lithium or a methyl Grignard reagent with selenium followed by protonation of the product. The compound is a metabolite.[1][2]
According to IR spectroscopy, νSe-H = 2342 cm−1. For the other homologues, νE-H = 1995 (E = Te), 2606 (E = S), and 3710 cm−1 (E = O) for methanetellurol, methanethiol, and methanol.[3]
