A magnetically recoverable copper–salen complex as a nano-catalytic system for amine protection via acetylation using thioacetic acid

Green synthesis of carbamates and amides via Cu@Sal-Cs catalyzed C–O and C–N oxidative coupling accelerated by microwave irradiation

“…With the optimized conditions in hand, we further investigated the scope of the reaction using different substituted benzaldehydes and amines as shown in Table 4 26 , 44 – 47 . A variety of aromatic aldehydes having electron-donating or electron-withdrawing substituents, regardless of their positions, participated well in the reaction, indicating no obvious electronic impact.…”

“…The experimental procedure followed for the synthesis of 2a using acetanilide (0.98 g, 7.24 mmol) substrate produced 1.83 g (97% yield, 99.5% purity) as a white crystalline solid: mp 182−185 °C (lit. 42 1-Acetamido-4-iodonaphthalene (2j). The experimental procedure followed for the synthesis of 2a using 1-acetamidonapthalene (1.34 g, 7.24 mmol) substrate produced 2.12 g (94% yield, 99.2% purity) as a light pink crystalline solid: mp 195−199 °C (lit.…”
