Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

The Enders SAMP/RAMP hydrazone alkylation begins with the synthesis of the hydrazone from a N,N-dialkylhydrazine and a ketone or aldehyde [14]. The hydrazone is then deprotonated on the α-carbon position by a strong base, such as lithium diisopropylamide (LDA), leading to the formation of a resonance stabilized anion - an azaenolate.
tert-Butanesulfinamide (also known as 2-methyl-2-propanesulfinamide or Ellman's sulfinamide) is an organosulfur compound and a member of the class of sulfinamides.Both enantiomeric forms are commercially available and are used in asymmetric synthesis as chiral auxiliaries, often as chiral ammonia equivalents for the synthesis of amines.
Applications in Green Chemistry: Humic compounds are emerging as cost-effective raw materials for producing valuable chemical commodities. Natural and modified humic preparations are used as surfactants, redox polymers, drug precursors, chemical weed and pest control agents, sorbents, and agents for remediating contaminated areas.
Green rust (SO 2− 4) synthesized under anaerobic conditions in the absence of dissolved oxygen. Green rust is a generic name for various green crystalline chemical compounds containing iron(II) and iron(III) cations, the hydroxide (OH −) anion, and another anion such as carbonate (CO 2− 3), chloride (Cl −), or sulfate (SO 2−
Tomislav Friščić holds the Leverhulme International Professorship and Chair in Green and Sustainable chemistry at the University of Birmingham.His research focus is at the interface of green chemistry and materials science, developing solvent-free chemistry and mechanochemistry for the cleaner, efficient synthesis of molecules and materials, including organic solids such as pharmaceutical ...
Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. [1] Green chemistry is based upon twelve principles, identified in “Green Chemistry: Theory and Practice” and adopted by the US Environmental Protection Agency (EPA). [2]
