One-pot synthesis of ultra-branched mixed tetradentate tripodal phosphines and phosphine chalcogenides
摘要:
Ultra-branched mixed tetradentate tripodal phosphines and phosphine chalcogenides have been synthesized by the exhaustive regioselective addition of secondary phosphines, phosphine sulfides and phosphine selenides to available tris(4-vinylbenzyl)phosphine oxide under free-radical conditions (UV irradiation or AIBN) in good to excellent yields.

An atom-economic green synthesis of tertiary phsophine sulfides has been developed based on catalyst- and solvent-free addition of secondary phosphine sulfides to diverse terminal and internal alkenes (hept-1-ene, cyclohexene, styrenes, allyl alcohol, vinyl ethers, vinyl sulfides, vinyltrimethylsilane, 1-vinylimidazoles, vinyl acetate). The reaction proceeds under mild conditions (80 °C, without solvent

Secondaryphosphinechalcogenides react with diacetone-d-glucose (DAG) in the systemCCl4/Et3N (70°C, 4–24 h) to afford DAG chalcogenophosphinates in up to 79% yield, thus paving a short way to optically active chalcogenophosphinates with glucosemoieties. As an example, a mild regioselective hydrolysis (70°C, aqueous MeCOOH) of DAG bis(2-phenylethyl)selenophosphinate) obtained leads to monoacetone-d-glucose

ABSTRACT Secondary phosphine chalcogenides, R2PX (R═(CH2)2Ph, Ph; X = S, Se), react with divinyl chalcogenides, (CH2═CH)2Y (Y = S, Se, Te), at the 2:1 molar ratio (80–82°C, 56–80 h) in the absence of both catalysts (initiators) and solvents to quantitatively afford the corresponding anti-Markovnikov diadducts. Even at the equimolar reactant ratio, the diadducts are the major products, though monoadducts
