why has no one ever tried other birch reductions
« on: December 18, 2003, 02:28:00 AM »
this is a quote from rhodium:

Dimethyl Ethylene gycol ether. Na/K - very soluble K - moderate Na, Li, Ca - None Ethyl Methyl Ethylene Glycol ether Na/K - slight Dimethyl Diethylene glycol ether Na/K - very soluble Diethyl Diethylene Glycol ether Na/K - slightly Ethyl Methyl Diethylene Glycol ether Na/K - Moderate Methyl n-propyl Diethylene Glycol ether Na/K - slightly (a) n-Butyl Methyl Diethylene Gycol ether Na/K - very slightly (a) TetraHydroFuran Na/K - slightly 1-Methoxymethyltetrahydrofuran Na/K - Very soluble 1-ethoxymethyltetrahydrofuran Na/K - moderate (b) 2-Methyltetrahydrofuran Na/K - very slightly (a) Dioxan Na/K - None Cyclic tetramer of propylene oxide Na/K - Very soluble 1: 2-Dimethoxypropane Na/K - very slightly (a) Triethylene glycol dimethyl ether Na/K - very soluble Tetraethylene glycol dimethyl ether Na/K - very soluble Ethylenediamine very soluble Na/K - very Methoxyethylamine Na/K - very soluble
(only on proplonged cooling to 193 K)
( slightly at room temp; moderate on cooling to 193 K)
This article goes on to state:

Lithium - doesn't dissolve in dimethylamine but is quite soluble in ethylamine

i mean, wouldn't it be worth a TRY? and so simple. ethylene diamine is totally uncontralled, for one, and wouldn't it be MUCH safer to work with than liquid NH3?
