A new strategy for the preparation of 3-halobenzo[b]thiophenes via a photo-driven halocyclization/demethylation 2-alkynylthioanisoles with simple alkyl halides was developed. The reaction can proceed smoothly at room temperature under visible-light irradiation without any external photocatalyst, and protocol has range advantages, including simplicity mildness conditions, good functional-group tolerance, excellent yields products.

A direct, aerobic and visible light photocatalytic approach to synthesize 4-thiocyanated 5-hydroxy-1H-pyrazoles via cross-coupling of pyrazolin-5-ones with ammonium thiocyanate is described. Under redox-neutral metal-free conditions, a series could be easily efficiently obtained in good high yields by using low-toxicity inexpensive as the source.
