Abstract As an important transition metalcatalyst, palladium is extensively used in many areas including electronics industry, petroleumindustry, automobile industry and fine chemicals engineering. However, it brings harm to the environment as well as people’s health. Herein, we managed to introduce a butynyl group to 1,2-dioxetane developing a reaction-based chemiluminescent probe as well as an
trace-level fluorideions. This sensory system comprises two steps: amplification and chemiluminescence. These steps were linked with chemical reactions and were induced continuously. The process from amplification to chemiluminescence was accomplished in this system using fluorideions. The amplification is based on a self-immolative system that permits the detection of emissions even at low fluoride ion

An enhanced chemiluminescence signal is obtained when electronically triggered dioxetane cleavage is initiated by fluoride-mediated deprotection of the silyl-protecting group, followed by self-immolation via 1,4-quinone-methide rearrangement. The reaction takes place even when the probe is trapped within a PMMA layer on top of a glass plate. In that arrangement, fluoride in aqueous solutions can be detected selectively at low micromolar concentrations.

Arylaldehyde acetals can be reacted with trimethyl phosphite to produce the corresponding dimethyl α-methoxybenzylphosphonates, themselves used in a WadsworthâEmmons reaction with adamantanone to produce hindered methyl vinyl ethers. These vinyl ethers are useful in the preparation of chemiluminescent 1,2-dioxetanes. The scope of the reaction has been explored.
