They proposed that the reaction proceeded via a zwitterionic intermediate.

A classic example of this might be the first stage of a reaction which proceeds via a transition state.

Neurulation in fish proceeds only via the secondary form.

Then he proceeded, via raised fingers, to give her his telephone number.

Two days later, she proceeded via the Palaus to the Philippines.

The reaction is thought to proceed via the following stoichiometry:

Reagents without such a weak bond would likely proceed via a different mechanism.

The aldol reaction may proceed via two fundamentally different mechanisms.

These reactions probably proceed via oxidative addition of the thiol.

The reactions appear to proceed via 1e steps, and rearrangement products are sometimes observed.
