Fischer synthesis
WebThe Fischer–Tropsch process (or Fischer–Tropsch Synthesis or F-T) is a set of chemical reactions that changes a mixture of carbon monoxide gas and hydrogen gas into liquid … WebThe Kiliani-Fischer synthesis is a method for synthesizing monosaccharides. It proceeds via synthesis and hydrolysis of a cyanohydrin, thus elongating the carbon chain of an aldose by one carbon atom while preserving stereochemistry on all the old chiral carbons. The new chiral carbon is produced with both stereochemistries, so the product of a ...
