In his seminal book about these compounds, Donald Cram came up with the MSAD scale, named for the last initials of four data contributors.
DePuy et al. developed a fluorodesilylation method to synthesize these compounds in the gas-phase. In his seminal book about these compounds, Donald Cram came up with the MSAD scale, named for the last initials of four data contributors. In 1984, Olmstead et al. reacted triphenylmethane with n-butyllithium and 12-crown-4 to produce a stable species of this kind. Thiamine pyrophosphate transforms into a compound of this type before undertaking a nucleophilic attack on a substrate. [2,3]-sigmatropic rearrangements in which one of these groups is adjacent to an (*) alkoxide, are known as Wittig rearrangements. The first step in an E1CB reaction mechanism is the formation of one of these species. The enol form of an enolate contains this reactive intermediate. This species, which has a trigonal pyramidal geometry, is the only reactive intermediate to follow the octet rule. For 10 points, name these chemical species in which an unshared pair of electrons make carbons negatively charged
