Credential scheme

These minimal structural requirements, called locality, are described in a little more detail in Section 5.3.1. Similar requirements would be made on general cryptologic transaction schemes, such as secrecy, payment, and credential schemes. Section 5.3.2 describes additional structural properties that characterize special classes of... 

The successful results and the green credentials of the process (water as cosolvent and only the nontoxic titanium dioxide as final residue) make this reaction an excellent, cheaper, and favorable alternative to the classical Strecker synthesis, which also requires the hydrolysis of cyanide to the amido group (Scheme 14.8c).

In a subsequent report, iron(iii) triflate could be used in combination with sodium borohydride for the hydrogenation of olefins (Scheme 12.22). The reaction operated well in a range of alcoholic solvents at ambient temperature, with the highest yields obtained using ethanol. This procedure provides an operationally simple method for the hydrogenation of alkenes, which can be conducted in solvents with excellent green credentials. 

MCRs driven by catalytic species possess all the credentials to be considered an ideal tool for organic synthesis in terms of atom economy and efficiency. In this section, an overview of such processes involving NHCs is discussed from two perspectives (Scheme 5.31) (i) NHCs acting as organocata-lysts and (ii) NHCs as ligands in transition metal-based catalysts.
