Is there an ion exchange between CaH2 and LiClO4 ?

Under what conditions? Not in aqueous solution- the calcium hydride will react with the water. Not if you melt them together (BOOM!).


yes i know, tell me a solvent then. it also react with alcohols.

I have some NH2 terminated liquids, does those work ? or glycols ?

also, ive got acetone.


The hydride is a very strong base and a pretty good nucleophile. It will react with alcohols, possibly also primary and secondary amine, and probably also ketones. I can see it either reducing acetone to calcium isopropoxide, or deprotonating it and starting a Claisen condensation (and that's assuming the acetone is dry, and not 5% water like most of it). If you're trying to make calcium perchlorate, there must be an easier way.


Nah i want lithium hydride.

Stereochemistry after a Suzuki reaction?

I am wondering that if we react e.g. a trans-cyclohexyl-2phenyl-boronic acid with a custom halide, let say bromobenzene, with Suzuki conditions, than will the cyclohexane ring keep it's trans stereochemistry for its two substituent?

Does anyone know where to purchase a bit of fine gold wire? I´m looking for 0.03-0.05mm diameter at a lenght of about 1-2m.

Pretty much any jewelry supplier will be able to get that for you. They should have it in an appropriate diameter, also, given how readily gold passes through a draw plate.

The standard setup is graphite anode with copper cathode. Are you looking to use the wire as the anode, cathode, or both?



As below, so above.
