Stereoselective Catalytic Synthesis of Alkynylated Phosphaethenes Leading to Activation-Free Gold Catalysis

The π-accepting property of alkene-like phosphaethenes (–P=Ca sterically encumbered gem-dibromophosphaethene by a Sonogashira process has been accomplished, and the corresponding 2-alkynyl-2-bromo-1-phosphaethenes were obtained. Subsequent arylation of the 2-alkynyl-2-bromo-1-phosphaethenes by the palladium version of the Kumada–Tamao–Corriu (KTC) reaction gave the corresponding 2-alkynyl-2-aryl-1-phosphaethenes through an inversion of the configuration. The 2-alkynyl-2-aryl-1-phosphaethenes were converted into the corresponding chloro-gold(I) complexes, and screening of their catalytic activity revealed that both appropriate π-conjugative substituents and the stereochemistry were decisive for the efficiency of the gold-catalyzed reactions under activation-free conditions. Chloro-gold complexes bearing 2,2-diaryl-1-phosphaethene ligands showed moderate-to-good catalytic activity.

Reaction of the Phospha-alkyne ArCP (Ar = 2,4,6-But3C6H2) with Nucleophiles: A New Approach to 1,3-Diphosphabutadiene Synthesis

The reactions of ArCP (Ar = 2,4,6-But3C6H2) with the nucleophiles MeLi and Li are described; the X-ray crystal structure of ArCP is also reported.

Photochemical C(sp)-C(sp2) Bond Activation in Phosphaalkynes: A New Route to Reactive Terminal Cyaphido Complexes LnM-CP

The photochemical activation of the C(sp)-C(sp2) bond in Pt(0)-ν2-aryl-phosphaalkyne complexes leads selectively to coordination compounds of the type LnPt(aryl)(CP). The oxidative addition reaction is a novel, clean, and atom-economic route for the synthesis of reactive terminal Pt(II)-cyaphido complexes, which can undergo [3 + 2] cycloaddition reactions with organic azides, yielding the corresponding Pt(II)-triazaphospholato complexes. The C-C bond cleavage reaction is thermodynamically uphill. Upon heating, the reverse and quantitative reductive elimination toward the Pt(0)-phosphaalkyne-π-complex is observed.

ArP=C=Si(Ph)Tip: The first allenic compound with doubly bonded phosphorus and silicon

The first allenic compound with doubly bonded silicon and phosphorus, the 3-phospha-1-silaallene 1, has been obtained by dechlorination of the corresponding (chlorosilyl)chlorophosphaalkene 10 with tert-butyllithium at low temperature. Compound 1 was char
