Protected & Silylated Alkynes
Alkynes carrying a protecting group: a trimethylsilyl or triethylsilyl cap on the alkyne carbon, or a tetrahydropyranyl ether on an adjacent hydroxyl. These entries exist for the middle of a sequence, where the group underneath has to survive steps that would otherwise attack it. The protecting group is removed under conditions that leave the rest of the molecule alone – fluoride for the silyl cap, mild acid for the THP ether.

Protected & Silylated Alkynes outside the catalogue
If the compound you need is not in this group but belongs to it chemically, send the structure. Most of what we make is not on the site: the catalogue is the part that is already characterised and packed.
A route review costs nothing and usually comes back within two working days with the step count and the likely purification burden.
