文摘

•: Ultrasound promoted facile three-component procedure to access 2H-indazoles.
•: Under ultrasonic irradiation, the yields dramatically increased.
•: Under ultrasonic irradiation, the reaction times considerably shortened.
•: CDSCS is highly active and selective nano-catalyst for 2H-indazole synthesis.
•: Reusability and inexpensive nature of the catalyst.
