OG Complex Work Unit Chemistry
in the formula (1),
R1 and R2 represent each independently a hydrogen atom, a C1-20 hydrocarbon group, a ring structure in which R1 and R2 are bonded to each other, or a ring structure in which a plurality of R1 or R2 are bonded to each other;
An− represents a deprotonated form of an organic sulfonic acid or organic disulfonic acid;
either one of n and m is 1, and the other is 2; and
a is 2 when Y is a carbon atom and 3 when Y is a phosphorus atom.
