aluminum galinstan 

Aluminum galinstan Al/GaInSn is an amalgam of aluminum and galinstan used for reductive amination. It's a useful and non-toxic alternative to aluminum mercury Al/Hg.

I heated galinstan and aluminum and stirred to make aluminum galinstan.

I reduced phenyl-2-butanone (or P-2-Bu), and ammonia in ethanol solution using aluminum galinstan and then filtered to make phenylisobutylamine, and dried it with anhydrous magnesium sulfate. Then reacted the phenylisobutylamine ethanol solution with hydrogen chloride gas to make phenylisobutylamine HCl. The liquid galinstan was recoverable and reusable.

Aluminum Galinstan 

Aluminum Galinstan (Al/GaInSn) is when a non-toxic amalgam of Aluminum and Galinstan. 95% Aluminum and 5% Galinstan (Gallium Indium Tin alloy). It's used for reductions and reductive amination.

I reacted ThioPhenyl-2-Propanone (TP2P) with freebase methylamine in ethanol distilled water solution and reduced it to Methiopropamine (MPA) using aluminum galinstan (Al/GaInSn).

I reduced diphenylmethanone into diphenylmethanol using Aluminum Galinstan.

Aluminum Galinstan amalgam plus Palladium on Carbon 

Aluminum Galinstan amalgam plus Palladium on Carbon is Aluminum Galinstan amalgam (25g to 100g Aluminum + 100g Galinstan) plus 500mg of Palladium on Carbon is something that can be used for an alternative to toxic Aluminum Mercury amalgam for reductive amination. Cyclohexyl-2-Propanone and Methylamine in Ethanol in a Carbon Dioxide inert atmosphere can be reduced to Propylhexedrine (Cyclohexyl-2-AminoPropane) and filter 90% of the Aluminum Hydroxide Ethanol water Propylhexedrine solution through a Buchner funnel with Zeolite careful not to spill over Palladium Galinstan amalgam, then add everclear to the remaining 10% in the round bottom flask, then filter 90% and you got 99% of Propylhexedrine ethanol water solution. Dry with Anhydrous Magnesium Sulfate, filter through Buchner funnel, pour in a beaker, then bubble dry HCl gas through the Propylhexedrine freebase to acid salt (Acid Salting) the Propylhexedrine into Propylhexedrine HCl salt. Palladium Galinstan is reusable for Aluminum Palladium Galinstan amalgam reductive amination.

Tony: I used Aluminum Galinstan amalgam plus Palladium on Carbon to synthesize Propylhexedrine from Cyclohexyl-2-Propanone Methylimine. Al/GaInSn + Pd/C . Al/Pd/GaInSn . Alternative to Al/Hg .

Aluminum Palladium Galinstan amalgam 

Aluminum Palladium Galinstan amalgam or Al/Pd/GaInSn is something that can be used for an alternative to toxic Aluminum Mercury amalgam for reductive amination. Cyclohexyl-2-Propanone and Methylamine in Ethanol in a Carbon Dioxide inert atmosphere can be reduced to Propylhexedrine (Cyclohexyl-2-AminoPropane) and filter 90% of the Aluminum Hydroxide Al(OH)3 Ethanol water Propylhexedrine solution through a Buchner funnel with Zeolite careful not to spill over Palladium Galinstan amalgam, then add everclear to the remaining 10% in the round bottom flask, then filter 90% and you got 99% of Propylhexedrine ethanol water solution. Dry with Anhydrous Magnesium Sulfate, filter through Buchner funnel, pour in a beaker, then bubble dry HCl gas through the Propylhexedrine freebase to acid salt (Acid Salting) the Propylhexedrine into Propylhexedrine HCl salt. Palladium Galinstan is reusable for Aluminum Palladium Galinstan amalgam reductive amination. Temperature 20°C to 30°C and reaction time 24 hours. Al/Pd/GaInSn .

Tony: I put 100g Galinstan (69g Gallium + 21g Indium + 10g Tin) and 50mg Palladium shot in a crucible and added 100g Aluminum foil to make Aluminum Palladium Galinstan amalgam. I used Aluminum Palladium Galinstan amalgam to do reductive amination on Cyclohexyl-2-Propanone Methylimine in ethanol in a Carbon Dioxide inert atmosphere to make Propylhexedrine. Then bubble HCl for Propylhexedrine HCl and clean it with Anhydrous Acetone to get rid of excess HCl. Temperature 20°C to 30°C and reaction time 24 hours.
