Experimental investigations of thermal stability of some morpholinecarbamic acid complexes of copper(II) and zinc(II)

Recent Advances in the Chemistry of Metal Carbamates

“…More in general, metal chlorido complexes can be used as precursors for the installation of carbamato unit(s) [166,171,[231][232][233] Other metal compounds, such as Dy(III) [235], Fe(II) [236], Cu(II) [237][238][239][240][241], Ni(II) [239] and Zn(II) [240][241][242][243] perchlorates, nitrates and sulfates, uranyl diacetate [244] Other metal compounds, such as Dy(III) [235], Fe(II) [236], Cu(II) [237][238][239][240][241], Ni(II) [239] and Zn(II) [240][241][242][243] perchlorates, nitrates and sulfates, uranyl diacetate [244] or [Pd(MeCN) 4 ] 2+ [245] were used as starting materials for the preparation of carbamato derivatives. The reactions are usually carried out in polar organic solvents (MeOH, MeCN) in the presence of amines, polyamines or aza-macrocyclic ligands under CO 2 atmosphere (Scheme 23a).…”

“…Other metal compounds, such as Dy(III) [ 235 ], Fe(II) [ 236 ], Cu(II) [ 237 , 238 , 239 , 240 , 241 ], Ni(II) [ 239 ] and Zn(II) [ 240 , 241 , 242 , 243 ] perchlorates, nitrates and sulfates, uranyl diacetate [ 244 ] or [Pd(MeCN) 4 ] 2+ [ 245 ] were used as starting materials for the preparation of carbamato derivatives.

“…The thermal degradation of homoleptic carbamates or oxido-carbamates under inert atmosphere usually proceeds quantitatively at temperatures below 500 °C with fragmentation of the organic groups, cleanly affording a metal oxide. The fate of the carbamato ligands during the pyrolytic process depends on the system; in general, multiple products have been detected in the gas phase, including CO 2 and the dialkylamine [ 42 , 240 , 333 , 334 ] ( Scheme 41 a). In some cases, the preferential formation of alkyl isocyanates and alkenes has been recognized ( Scheme 41 b–d) [ 335 , 336 ].…”
