Patent ID: 8182785

Claim:
A method of producing singlet oxygen, comprising: (a) decomposing, in the presence of a base, a mono-activated dihydroperoxide derivative of formula (1): wherein: R1 and R2 are independently chosen from: methyl, primary alkyl, secondary alkyl, alkoxyalkyl, haloalkyl, and oxoalkyl, or R1 and R2 together form an aryl, cycloalkyl, or arylalkyl, and X is chosen from: acyl, carbonyl, carboxyl, sulfonyl, sulfoxyl, phosphoryl, carbamyl, aryl, vinyl, and imidyl; and (b) producing singlet oxygen; wherein the base is of sufficient strength to deprotonate the hydroperoxide of the mono-activated dihydroperoxide derivative of formula (1).
