One class of compounds I haven't seen mentioned yet are alkynes.

In organic synthesis classes we've had to synthesise a number of small alkynes and all of them were really awfull, with a very low smelling threshold. Couldn't wash the smell of your hands or out of your clothes very well.

I remember the smell of phenylacetylene, but it's fresh-baked bread compared to phosphines.

In undergrad I made quite a few batches of 3,5-dithiahepta-1,6-diyne. Basically https://en.wikipedia.org/wiki/2,4-Dithiapentane but with ethynyl groups on the ends instead of methyl. It made the whole lab smell like weird truffles. Years later I still don't like truffles very much.

I agree that phenylacetylene isn't bothersome.
