Amidoximes represent a class of organic compounds that have a wide range of biological, pharmacological and technological applications. In view of the potential of these compounds, the objective of this paper was to provide an overview of the technological aspects and impacts of amidoximes through the analysis of patent deposits and the number of articles published. The research was conducted using the terms "Amidoxima", "Amidoxime" and "Amidoxim" in the INPI, LATITAP and ESPACENET patent databases, as well as in the journals search platforms of the Web of Science TM , Scopus and Scielo. The International Patent Classification (IPC) indicated the greatest use of amidoximes in C07 (Organic Chemistry), with a total of 42 documents deposited. The United States stands out as the largest patent holder for amidoximes, with 34 applications, which corresponds to 20.5 %. In addition, in general, research on journal platforms revealed that scientific production focuses on studies involving the synthesis and structural characterization of these compounds, application in the industry and description of biological and pharmacological activity. The research involving the term "Amidoxime" provided a h-index equal to 57, and revealed that Brazil does not have many patent documents deposited (only 2), and the number of articles published were 9, which demonstrates the need for Incentives to encourage Brazilian researchers to patent their research.

“…Typically, suitable properties of catalyst support materials are: (i) environmental friendliness, (ii) high chemical and thermal durability, (iii) low cost, (iv) inertness against air and moisture, and (v) ease of chemical modification. Apple seed, rich in starch, can be introduced as a very exciting option, as it has all the desired properties of catalyst support, and it is considered to be biodegradable, and on the other hand, most of the time is disposed of as waste, and there have been limited reports in the literature about its use . To the best of our knowledge, there is no published research on the use of apple seed starch as a catalyst support.…”

From the perspective of green chemistry, in catalytic systems, being low cost and eco‐friendly, in addition to high chemical and thermal stability, are requirements of support materials. In this regard, we used apple seed starch as an accessible, nontoxic, and cost‐effective support material. In order to take advantage of magnetic separation, the magnetite nanoparticles were chosen as an ideal pair for apple seed starch. Furthermore, during the Schiff base reaction, the magnetic apple seed starch was functionalized with 2,2′‐furil along with amine functionality to be used as a bio‐support for immobilization of cobalt. The introduction of cobalt had a significant effect on the greenness of the catalyst and reducing its price. FT‐IR, TGA, XRD, FE‐SEM, TEM, VSM, ninhydrin test, element mapping, AAS, and EDX analysis were applied to characterize the newly prepared catalyst. The effectiveness of this novel Schiff base supported catalyst was evaluated in the Mizoroki–Heck and the Suzuki–Miyaura coupling reactions. High reactivity and selectivity were among the most prominent characteristics of the catalyst as compared to previously reported catalysts. The longevity test and hot filtration showed the ability to use the catalyst at least 5 times and negligible cobalt leaching during the reaction, respectively. This work is the first report on the usage of apple seed starch as a supporting catalyst and 2,2′‐furil as a ligand in the catalyst modifications and catalytic activity. Accordingly, this can be the beginning of an attractive way in the design and synthesis of heterogeneous catalysts.
