The obtained Nheterocyclic carbene precursors were investigated in an asymmetric benzoin reaction. All newcompounds were fully characterized, and the absolute configurations were determined via X-ray diffraction and NOESY measurements.20232023-12-11 09:22:25Članek v reviji152885UDK: 547.8.057ISSN pri članku: 1420-3049DOI: 10.3390/molecules28247973COBISS_ID: 176421635sl
