Now he has struck on an idea that may give his beloved carpet the synthetic equivalent of eternal life.

Like methyllithium, it is the synthetic equivalent to the methyl carbanion synthon.

A synthon and the corresponding commercially available synthetic equivalent are shown below:

Of course, both synthons do not exist per se; synthetic equivalents corresponding to the synthons are reacted to produce the desired product.

As a result, synthetic equivalents have been developed that are simpler to produce and apparently at least as effective.

Since paraldehyde has better handling characteristics, it may be used indirectly or directly as a synthetic equivalent of anhydrous acetaldehyde (b.p. 20 C).

It is the synthetic and reactive equivalent of an acyl carbocation, but the actual structure has the oxygen and carbon linked by a triple bond.

It is commonly used as the synthetic equivalent of a Ph synthon.

Methyllithium is mainly used as the synthetic equivalent of the methyl anion synthon.

In organic synthesis, EtBr is the synthetic equivalent of the ethyl carbocation (Et) synthon.
