Complete the following reactions: a. b. c. d. e. f. g. h. i. |
Answer» Solution :a.  B.  c.  d. `R_(2)CuLi` does not add to `(C=O)` bond but couples.  e. This is an example of `1,4-`ADDITION or conjugate addition to an `alpha,BETA-`unsaturated carbony1 compound.  f. It is an example of partial oxidation of `(CH_(3))` to `(-CHO)` (Etard type reaction). Only terminal `CH_(3)` is oxidised to `(-CHO)`.  Formation of acetral ester prevents further oxidation of the intermediate aldehyde to acid `(-COOH)` group. g.  h. It is an example of Gattermann-Koch synthesis. The reaction TAKES place at `rho-`position.  i.
