Neutral boron [(L1-3)BPh2] and cationic charged boron [(L1a-3a)BPh2] complexes for chemical CO2 conversion to obtain cyclic carbonates under ambient conditions

Three neutral salen ligands (L1-3) with three cationic charged salen ligands (L1a-3a) and the corresponding neutral boron [(L1-3)BPh2] and cationic charged boron [(L1a-3a)BPh2] compounds have been successfully synthesized and characterized under ambient conditions.
