Web2 days ago · Organometallic chemistry is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. Webfirst example is the Grignard and the organolithium reagent. The organometallic reagent (M = Mg or Li) attacks the carbonyl carbon and the C=O bonds breaks at the same time to give the tetrahedral intermediate with a negative charge on the oxygen.
