Conceptual Foundations

The presented study examines the concepts of “environmental marketing” and “environmental product”. The study attempts to conceptualize these terms in Russian language with allowance for the concept of sustainable development and the principles of the circular economy.Aim. The study aims to develop the conceptual foundations of environmental marketing and its derivative — environmental product, laying the groundwork for future research in specifying the concepts of “environmental marketing” and “environmental product”.Tasks. The authors examine the current state of environmental marketing and environmental product in Russia in terms of legislation and market practices; analyze the evolution of these concepts in foreign and Russian publications; systematize experience in this field; provide an original conceptualization of these terms; operationalize their key characteristics and features.Methods. This study is based on qualitative empirical research using such methods as content analysis, synthesis, formalization, and systematization. The theoretical and methodological approach of the study is based on the works of foreign and Russian scientists in the field of environmental marketing, the “green” approach to the promotion of goods, and sustainable enterprise development.Results. A research gap in the conceptualization of “environmental marketing” and “environmental product” in Russian language is identified. The authors provide an original interpretation of these concepts with allowance for the principles of sustainable development and “green” promotion.Conclusions. This study serves to elaborate on the scientific meaning of the concept of “environmental friendliness” applicable in marketing, changing the trend of the increasing number of products that fall under the definition of greenwashing. The published materials can be useful for environmental consultants, marketers, and representatives of legislative authorities in certifying products according to environmental standards.

Zinc sulfamate (Zn(NH2SO3)2 is a derivative of sulfamic acid (H3NSO3) which possesses “Lewis acidity” and finds well suited in a number of catalytic applications. The present paper describes an efficient, eco-friendly, and clean synthesis of 2-substituted benzimidazole derivatives by reacting diverse o-phenylenediamine with various substituted aromatic aldehydes using a catalytic amount of zinc sulfamate in ethanol at ambient temperature. As a result, 10 mol.% of Zinc sulfamate catalyst showed 92% of respective product yield with 100% conversion using short reaction period in ethanol. Meanwhile, effect of reaction parameters, such as amount of catalyst, different solvents, and reaction temperature on reaction product, was also studied. In addition, in the optimized reaction condition various substituted biological important benzimidazoles derivatives were prepared by using optimized reaction condition in good to efficient yield. In addition, possible reaction mechanism in the presence of zinc sulfamate for the preparation of benzimidazole derivative was sketched and discussed. The present green approach showed significances with faster reaction rate with inexpensive catalyst, which showed excellent and clean yield of benzimidazole in mild reaction condition with easy work-up procedure.
