Presentation Transcript

  1. Grignard Reagents

  2. Organolithium reagents

  3. RMgX and Rli Bond Type

  4. Structure of RMgX and RLi

  5. RMgX and RLi as Bases • They remove the following types of protons readily

  6. Gilman Reagents • Coupling with a vinylic halide is stereospecific; the configuration of the carbon-carbon double bond is retained.

  7. Reaction of Gilman Reagents with Epoxides • Ring opening is regioselective.

  8. Carbene • In its lowest electronic state, carbon is sp2 hybridized with the unshared pair of electrons occupying the third sp2 orbital.

  9. Dihalocarbene
