The study of THF models may providea valuable class of reagents for group transfer reactions with practical significance. Onlya few researches about 5, 10-methenyl-THF models have been reported in literature.展开更多
Four 1, 2, 3-trisubstituted imidazolinium iodides which were used as 5,10-^+CPh-THF model (7-10) at formic acid oxidation level were synthesized.

The benzylidyne group (phenyl- substituted one carbon unit)transfer reactions from these compounds to Grignard reagent were in- vestigated, and the reactions of these compounds with KBH_4 and NaOH were also studied.展开更多
