Abstract:
(Hydroxymethyl)phosphorus compounds are well-known and valuable compounds in general; however the use of (hydroxymethyl)phosphinates R(1)P(O)(OR(2))CH(2)OH in particular has been much more limited. The potential of this functionality has not yet been fully realized because the mild unmasking of the hydroxymethyl group was not available. The mild oxidative conversion of R(1)P(O)(OR(2))CH(2)OH into R(1)P(O)(OR(2))H using the Corey-Kim oxidation is described. Other reactions preserving the methylene carbon are also reported.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

Introduction to Functional Groups
Functional groups are group of atoms with specific chemical properties that occur within organic molecules and sometimes denoted as “R”. Functional groups are found along the carbon backbone of macromolecules can form chains or rings of carbon atoms. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
