Synthesis of Novel Cobalt(III) Porphyrin−Phosphoryl Complexes
摘要:
Novel porphyrinato[phosphoryl] cobalt(III) complexes were synthesized unexpectedly through the reaction of BrCoIII(por) (por = porphyrinato dianion) with Me3SiLi (MeLi-Me6Si2-HMPA) and MeLi in HMPA at -78 degrees C. Phosphoryl complexes were also synthesized from HMPA-K and the appropriate organophosphoryl chloride-K. As a result, Me3SiLi may not always be an appropriate silylating agent for bulky organometallic electrophiles.

transfer from (2,4-dimethylphenyl)(fluoromethyl)(phenyl)sulfonium tetrafluoroborate to unactivated alkenes. The fluorocarbene or fluoromethylene synthon is the smallest “organic” node in a molecular graph of the organofluorine compounds. In this work, we present alternative solution to unavailable fluorodiazomethane (CHFN2), a missing one-carbon C1 piece in fluorine chemistry, by using a fluoromethylsulfonium
