Dehydration of 2-hydroxy-8-R-tricyclo[7.3.1.0(2.7)]tridecan-13-ones (R = H, Me, Ph) effected by various reagents provided 8-R-tricyclo[7.3.1.0(2.7)] tridecen-13-ones with different positions of the double bond. In the presence of phosphoric acid arise isomers with the double bond in 2(3) position, a mixture of hydrochloric and acetic acid primarily affords isomers with the double bond in 2(7) position that further migrates into 7(8) position at R = Me, Ph.
Deuterium-based i.e. isotopic hydrogen chemiluminescent 1,2-dioxetanes derived from the photo-oxidation of new novel alkenes which are synthesized by the coupling reaction of (a) a saturated or unsaturated cyclic, polycylic, normal or branched chain alkyl, cycloalkyl and spiro-fused and (b) substituted aromatic esters or ketones wherein (a) or (b) or both at least have a deuterium atom or a deuterium atom-containing group. These deuterium-based 1,2-dioxetanes may also have electron donating or withdrawing groups at the four-membered peroxide ring. Thus, the added electronic charge and the isotopic hydrogen or isotopic hydrogen-containing group hereof affects the light producing efficiency of 1,2-dioxetanes.
A method of generating light through chemiluminescence involves providing a stable 1,2-dioxetane of the formula:
1
Wherein (a) R
1
and R
2
are each, individually, a chemical reactive site or when fused together form a chemical reactive site, and R
3
and R
4
are each, individually, a chemical reactive site or when fused together form a chemical reactive or (b) R
1
has at least two hetero atoms with chemical reactive site and R
3
and R
4
are inactive site and R
2
is a chemical reactive site.

A chemiluminescent 1,2-dioxetane includes an alkaline phosphatase triggerable stable 1,2-dioxetane; a polymeric enhancer which is either an ammonium or phosphonium salt of a polyvinylbenzyl chloride and an aqueous enzyme diluent or stabilizer which corresponds to blood component including blood protein. The system is efficacious for single molecule detection of alkaline phosphatase and other enzymes.
