About を契機に
を契機に is a grammar construction made up of を, the noun 契機 'chance' or 'trigger' and に. It is a formal pattern that is used to indicate some sort of trigger and may be translated '(A) led to (B)', 'as an opportunity to (A), (B)', or 'as a result of (A), (B)'. (A) may either be a positive or negative event, but will usually be something extremely big in terms of life, or current/historical events in the world.
を契機に will be seen after nouns, or verbs that have been nominalized with either の or こと.
Alternatively, にして or として may replace に without any change in the overall meaning.
Caution
Unlike をきっかけに, を契機に will almost exclusively be used in relation to some turning point or critical juncture. Due to this, it can sound quite unnatural when used to express a trigger that would not be considered a big event.

What is the difference between を契機に and をきっかけ?
wrt7MameLZE33wlmpCAV
The details for this grammar point indicate it can be written ~にして・として, but none of the examples show this usage and both are simply marked wrong. Under what circumstances are these variations used?
