WebThe structure of the thin bismuth layer might be affected by laser radiation-induced disordering and oxidation [29,30]. To eliminate possible laser radiation effects, extremely low (0.05 mW) laser power was employed. No Raman bands related to bismuth oxidation products were observed. The parameters of the Raman bands are listed in Table 4. WebMar 29, 2024 · A new bismuth(V) oxidative catalytic system has been developed and applied for the conversion of hydrazones into diazo compounds. With the use of low catalytic amounts of Ph3Bi and AcOH with NaBO3·H2O as a terminal oxidant, the in situ formation of Ph3Bi(OAc)2 is capable of oxidizing hydrazones in excellent yields.
