Disclosed is a process for producing a heterocyclic compound having as the side chain group a nitromethylene group of the formula: ##STR1## wherein Y, R and n are as defined in the specification, which comprises reacting a 2,2-dihalonitroethylene compound with a 1-aminoalkanethiol compound or a 1-N-substituted derivative thereof.
exposure may accelerate subsequent proton reduction under visible light irradiation (λ > 420 nm). The hydrogenevolution rate (HER) and apparent quantum yield (AQY) at 420 nm of modified CMPs were increased up to 27.2 times and 47.1 times in comparison to those of original CMPs. Photocatalytic H2 evolution activity evaluation of BBT-SC2CH3, BBT-SC2N(CH3)2 and SC2NHAc in which amino groups were replaced
