A reaction product of a dithiol compound and a diene compound having a high refractive index, a high Abbe number, excellent transparency and heat resistance, a production method thereof, and at least one of the sulfur-containing compounds as one of the constituent components, Provision of optical materials. A dithiol compound represented by the following general formula (II) and a diene compound represented by the general formula (III) are reacted to form a sulfur-containing compound having an Abbe number (νd) of 40 or more. HS-G 1 -SH (II) , G 2 "(III) (G 1 is sulfur and / or oxygen atom may contain an aliphatic or alicyclic hydrocarbon group, an optionally substituted aromatic group or a condensed A polycyclic aromatic group. G 2 ″ is an aliphatic or alicyclic group having two or more carbon-carbon double bonds and may contain at least one atom of oxygen, nitrogen, sulfur or silicon. A hydrocarbon compound, an aromatic or condensed polycyclic aromatic hydrocarbon compound which may be substituted). [Selection figure] None |
