Purinescan be formed in water under abiotic conditions from simple organic precursors and are ubiquitous in living organisms, present in nucleotides, coenzymes and innucleic acids, RNA and DNA. This chapter covers theoretical studies, spectroscopic characterization, synthesis, and reactivity of purines ...
Irrespective of their definition, the ionic character of ILs enables different cation–anion arrangements and a consequent formulation of unique, tunable, and versatile compounds. The structural diversity of ILs resulted in the upsurge of a great number of applications, such as metal recovery, ...
