A question about the use of "as to..."

[batmura]

Could someone please clarify the use of "as to..."?

What I'd specifically like to know is whether "as to..." should strictly be followed by a noun or whether a noun clause is also acceptable.

To exemplify; are the sentences below correct or not

As to why I didn't enjoy the party, there were too many people I didn't know.

As to the reason why I didn't enjoy the party, there were too many people I didn't know.

Thanks!

Hello Batmura, welcome to UE!

Yes, both those sentences are fine. A noun, a noun phrase, or a complete clause can serve as the object of "as to".

All the best,
