Organic Reactions And Their Mechanisms
I * i' K n R Na+ 60 OH O the acyloin Scheme 16.42 base catalysed ester
condensations can compete (e.g., Dieckmann reaction). Thus it may be essential
to trap the ethoxide ion (see, Scheme 6.2) as it is formed. This is done by
including ...

Polarity Control for Synthesis
The exception may be the acyloin condensation [ Bloomfield. 1976]. The acyloin
condensation couples two ester groups to form an a-ketol via the radical anions.
The most attractive feature of this process is that, for the intramolecular version, ...
