“…A notable advancement towards greener methods involves the replacement of conventional iridium-based photocatalysts with organic counterparts, such as 4CzIPN in our work. 114 Atom economy is a central principle in green chemistry, assessing the efficiency of chemical reactions by measuring atom utilization and reducing the ecological impact (waste). Previous photocatalytic HAM methodologies generally made use of potassium alkyltrifluoroborates, phthalimide redox handles, Hantzsch esters and alkyltrimethylsilanes.…”

“…For any individual chemical reaction, the mass of waste generated may be generally considered to originate from seven sources: by-products (BP) arising as a mechanistic consequence in producing the target product, side products (SP) arising as a consequence of competing reactions not leading to the intended target product, unreacted excess reagents (XS), catalysts and ligands (CAT), reaction solvents (RS), work-up materials (WU), and purification materials (PU). If P m is the mass of the desired target product of the reaction, then the total mass of waste and the E-factor are defined according to equations (1) and (2) shown below.…”

“…The use of green chemistry metrics is now a well-established tool used by synthetic organic and process chemists to estimate the material efficiency, environmental impact, and safety-hazard impact of their synthesis plans and chemical processes to a desired target molecule [1,2]. More importantly, it is a powerful tool in making decisions about which candidate synthesis strategies to choose and ultimately to actualize in the pursuit of "green" syntheses at the early design and planning stages of a synthesis campaign.…”

“…Strict metrics using a holistic cost assessment are needed to guide us beyond the original 12 Principles of Green Chemistry, which are very valuable, but are largely qualitative. As cost accurately reflects all impacts, using cost is also more meaningful than other metrics, such as Process Mass Intensity (PMI), that have become popular lately but do not fully account for expensive but low mass reagents or catalysts. , A further “greening” of organic chemistry will require the tools and expertise of the process chemistry community to perform cost calculations that reflect true cost assessment.…”
