An efficient and recyclable catalytic system for carbon-sulfur coupling reaction and synthesis of 5-substituted 1H-tetrazoles

In this research paper, efficient and economical protocols for the synthesis of symmetrical sulfides and 5-substituted 1H-tetrazoles have been reported using Fe3O4@SBTU@Ni(II) as a heterogeneous and recoverable nanocatalyst. The noticeable features of this catalytic system are: operational simplicity, environmentally benign, easier work-up procedure, green and efficient synthetic entry to excellent yield of products in a high reusability and applicability to various starting materials and, therefore, cost efficiency.
