Molecular rearrangements of excited states generated by intramolecular dioxetane scission. Photochemistry without light. Mechanistic and exploratory organic photochemistry
The electrophilic character of carbenoïds can be activated by addition of organocopper reagents (RCu, R2CuM, or RCuZM), forming an unsymmetrical cuprate. Internal substitution of the carbenoïd halogen by the R group leads to a new alkylated unsymmetrical cuprate reagent. R can be primary, secondary, or tertiary alkyl, aryl, thiophenyl.

Organoboranes react with phosphorus-containing carbenoids to produce a variety of functionalized organophosphorus compounds under mild conditions. In some cases, selective migration of one group attached to boron can be observed. Phosphonite-borane complexes are introduced as novel synthons for the synthesis of phosphinic esters.
