solid anhydrides to give diamides (therefrom imides) or amidic carboxylic salts or imides, with solid imides to give diamides, with solid lactones or carbonates to give functionalized carbamic esters, with polycarbonates to give degradative aminolysis, and with solid isothiocyanates to give thioureas. Diamides give imides by solid-state thermolysis or acid catalysis. Various double, two-step, 3-cascade

Crystalline reagent capsules were prepared by installing CH3NCS into networked molecular capsules. While the tight encapsulation completely prevented leaching of reagent molecules into the supernatant, introduction of amines into the interstitial pores triggered reagent delivery. As a result, enhanced substrate selectivity was observed in crystalline‐state thiocarbamoylation (see picture; 86:14 in
