Fundamental and Principles of Green Synthesis

Synergistic applications of cyclodextrin-based systems and metal–organic frameworks in transdermal drug delivery for skin cancer therapy

“…water photolysis, CO 2 reduction) while a process with DG o 0 is actually the photocatalysis. 38 As far as concerned chemical methods, 29 the most important practical elements are the use of green solvents and catalysts that do not cause risks for the environment. Moreover, the use of appropriate catalysts usually ensures the reduction of waste compounds and byproducts.…”

“…A famous and effective physical method, 29 is the mechanochemical synthesis of the desired products using a ball mill apparatus. In this case, mechanical energy is used for the synthesis of different derivatives such as polymers, coordination compounds, biological molecules ( e.g.…”

“…The concept of biological synthetic methods 29 includes the use of microorganisms, plants and animals for their ability in synthesizing compounds or nanoparticles without the use of toxic chemicals. This class of methods is based on using the secondary plant metabolites extracted from seed, root and leaf as reducing or stabilizing agents.…”

Green synthesis of sulfur-containing polymers by carbon disulfide-based spontaneous multicomponent polymerization

“…The principles of “green synthesis” involve promoting sustainability, reducing energy consumption, minimizing toxic reagents and products, minimizing harm to the ecosystem, mitigating the risk of global warming, utilizing naturally available resources, generating byproducts in a rational manner, etc. 18,19 Our groups have established a series of alkyne-based spontaneous click polymerizations, such as spontaneous amino–yne click polymerizations, which just comply with the above principles, and from which regio- and stereoregular polymers were efficiently prepared. 20,21 The spontaneousness of the reaction relies on the activation of ethynyl groups by covalently connecting with electron-withdrawing ester, carbonyl, or sulfonyl groups.…”
