7-5 Preparation of Alkynes A. Alkylation of Acetylide Anions with Methyl and 1°
Haloalkanes As we have already seen, an acetylide anion is a strong base. An
acetylide anion is also a nucleophile; it has an unshared pair of electrons that it
can ...

Synthesis: Carbon with No Attached Heteroatoms
Acetylide anions do not require the presence of electron-withdrawing groups for
stabilisation, the carbanion being stabilised sufficiently as a result of the high 5
character of the carbon atom. Addition of acetylide anions to electrophilic centres
...

Organic Chemistry, Enhanced Edition
The presence of a negative charge and an unshared electron pair on carbon
makes acetylide anions strongly nucleophilic. As a result, they react with many
different kinds of electrophiles. Problem 8.9 The pKa of acetone, CH3COCH3, is
19.3.

Organolithiums in Enantioselective Synthesis
A model for the rather unreactive species, which is formed after 50% conversion,
is given by the 3:1 tetramer 29, which forms, according to NMR investigations,
from three equivalents of alkoxide 26 and one equivalent of acetylide 25 [88].

Molecular Organometallic Materials for Optics
As expected, the quadratic hyperpolarizability [11, 19, 144–147] increases upon
increasing the chain length of the acetylide bridge (e.g., 36 vs 37, b1.06(HRS) =
351 × 10−30 esu; b0(HRS) = 55 × 10−30 esu, for the latter) [145], and increasing
