Multi-step organic synthesis using solid-supported reagents and scavengers: a new paradigm in chemical library generation

Reactions of synthesis gas

PROBLEM TO BE SOLVED: To perform molecular weight measurement and separation of a fluorine containing organic substance slightly soluble in a general organic solvent by means of size exclusion chromatography by using a solvent containing dichloro pentafluoropropane as a mobile phase and using polymethyl methacrylate with a known molecular weight as a molecular weight measurement standard specimen. SOLUTION: As a mobile phase. a solvent containing HCFC225 such as a solvent containing only HCFC225 and a mixture solvent containing HCFC225 and other solvents are available. HCFC225 is selected from one or more kinds of substances selected from chlorinated fluorinated hydrocarbons with a molecular formula represented by C3 HF3 Cl2 . As the HCFC225, several kinds of isomers with the same molecular formula and different structures are known, however, HCFC225ca (CF3 CF2 CHCl2 ), HCFC225cb (CF2 ClCF2 CFHC1), and a mixture of them are desirable. As a molecular weight measurement standard specimen, polymethyl methacrylate with a known molecular weight is used.

The utility of two-phase water-organic solvent media for organic synthesis is widely recognized. Nearly all reported examples of this methodology involve transport of a reactant from the water phase into the organic phase where it encounters a second reactant to effect reaction. This process commonly known as phase-transfer catalysis (PTC) is the subject of numerous reports and reviews. The literature includes a few examples of a complementary synthetic procedure in which an organic solvent soluble reagent is activated by conversion to an ionic intermediate and transported to the aqueous phase for reaction. The recent report by Mathias and Vaidya describes a new example of this virtually unexplored methodology, which they have named inverse phase-transfer catalysis (IPTC). They report here some preliminary results from their continuing investigation of multiple-phase systems as media for organic reactions which provide significant new insight into the IPTC process.
