Abstract:
We present an advancement in synthesizing organophosphorus compounds via chemoselective phosphorylation achieved by a palladium and SelectPhos ligand system (Pd/L1). This catalysis system exhibits remarkable chemoselectivity, even in poly(pseudo)halide substrates and overcoming toxicity and substrate scope limitations. The catalytic system is robust, which is demonstrated across diverse substrates such as chloroaryl and bromoaryl triflates. Furthermore, we present a one-pot sequential strategy combining phosphorylation with Suzuki-Miyaura coupling, providing a versatile platform for the efficient synthesis of complex organophosphorus compounds, challenging conventional reactivity paradigms.

Aldehydes and Ketones to Alkenes: Wittig Reaction Mechanism
The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
