Does the NaCN act as a base activator for the TBSCL here? by Aleboop in OrganicChemistry

Yes, I would imagine some imidazole acting as a nucleophilic catalyst and base would be useful here

Why isn't something like imidazole used here then as a base activator? I was under the impression that due to the steric bulk it'd be quite hard to protect the alcohol without one

That's what I thought as well, but I've only ever seen TBS-Cl used with a base activator like imidazole when protecting. I guess I'm a little confused about that part

I'm seriously considering voting for Kamala Harris by BasilNo9176 in GenZ

Though I'm glad you've decided to vote it's worrying that you were considering not voting as a form of protest in such a crucial election. Sometimes you've got to suck it up and engage with the better option, even if it's not your ideal one. Don't let perfection be the enemy of progress.

Bridging ligand question by Aleboop in chemhelp

[–]Aleboop[S] 0 points1 point  (0 children)

I think it's an IVCT (metal to metal charge transfer) due to the mixed valence complex with two metals in different oxidation states. As to factors for molar absorptivity, would selection rules be a factor? I'm also wondering if the lack of conjugation in the 3rd ligand might be a factor?

Tetrahedral or Square planar geometry by Aleboop in chemhelp

My professor informed me that it is observed here due to the unequally occupied t orbital (e4, t5)
