Lub melting point feem ntau ntog nyob rau hauv thaj tsam ntawm 92-96 degree. Nws yog yooj yim soluble nyob rau hauv cov organic solvents xws li dichloromethane, tetrahydrofuran, toluene, thiab diethyl ether, thaum nws yog insoluble nyob rau hauv dej thiab aliphatic hydrocarbons xws li hexane. Cov molecule muaj ib lub hauv paus phosphorus atom bonded rau ob pawg phenyl thiab ib pawg benzyl. Lub phosphorus atom nqa ib khub ntawm electrons, ua rau nws nucleophilic thiab muaj peev xwm ntawm kev sib koom tes rau kev hloov hlau. Lub compound yog huab cua{11}}rhiab heev, maj mam oxidizing rau cov phosphine oxide coj mus rau lub sij hawm raug oxygen. Nws yuav tsum tau muab cia rau hauv ib qho chaw inert nyob rau hauv ib lub thawv kaw ntom ntom, tiv thaiv los ntawm lub teeb thiab noo noo, thiab khaws cia rau hauv qhov chaw txias. Kev sib cuag nrog cov neeg muaj zog oxidizing yuav tsum nruj me ntsis zam.oided.

Benzyldiphenylphosphine yog tertiary phosphine featuring ib pawg benzyl thiab ob lub phenyl rings txuas rau trivalent phosphorus atom. Cov qauv no belongs rau chav kawm ntawm monodentate phosphine ligands dav siv hauv kev sib koom ua ke chemistry thiab homogeneous catalysis. Lub phosphorus atom muaj ib tug stereochemically active ib khub uas muaj peev xwm pub electron ceev rau cov hlau chaw, tsim kom ruaj khov complexes nrog hloov hlau xws li palladium, nickel, rhodium, thiab ruthenium. Cov pab pawg benzyl qhia txog qib ntawm kev hloov pauv yooj yim thiab steric hloov pauv piv rau triphenylphosphine, cuam tshuam rau cov khoom siv hluav taws xob thiab steric ntawm ligand. Cov nplhaib uas muaj ntxhiab pab txhawb rau tag nrho lipophilicity thiab tuaj yeem koom nrog π- cuam tshuam nrog substrates lossis lwm yam ligands. Raws li ib qho tseem ceeb ligand nyob rau hauv organometallic chemistry, qhov sib xyaw no sib npaug electron - pub muaj peev xwm nrog kev nkag mus tau zoo, ua rau nws tsim nyog rau ntau yam kev hloov pauv catalytic.

Ligand hauv Hla -Coupling Catalysis
Benzyldiphenylphosphine yog dav siv los ua ib qho kev txhawb nqa ligand hauv palladium-catalyzed cross-kev sib txuas lus, suav nrog Suzuki-Miyaura, Heck, thiab Sonogashira couplings. Nws cov hluav taws xob- nplua nuj xwm txhim kho oxidative ntxiv cov kauj ruam, thaum nws cov steric profile txhawb kev txo qis, ua rau kev txhim kho catalytic efficiency thiab xaiv. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov tshuaj tiv thaiv uas cuam tshuam nrog cov substrates nyuaj lossis qhov xav tau me me.

Precursor rau Chiral Ligand Synthesis
benzyl pab pawg muab ib tug kov rau ntxiv functionalization los tsim chiral phosphine ligands rau asymmetric catalysis. Los ntawm kev qhia txog cov chaw stereogenic los yog chiral auxiliaries ntawm benzyl moiety, derivatives ntawm no compound tuaj yeem npaj rau enantioselective transformations xws li hydrogenation, allylic alkylation, thiab hydroformylation. Cov chiral ligands yog cov cuab yeej tseem ceeb hauv kev sib txuas ntawm cov tshuaj ntshiab enantiomerically thiab agrochemicals.

Coordination Chemistry thiab Hlau Complexes
Cov phosphine no ua haujlwm raws li tus qauv ligand rau kev kawm txog kev sib koom tes ntawm tertiary phosphines nrog ntau yam kev hloov hlau. Nws cov complexes raug tshawb xyuas rau lawv cov qauv, hluav taws xob, thiab catalytic zog, muab kev nkag siab txog cov hlau -phosphorus bonding thiab ligand cuam tshuam rau kev ua haujlwm. Cov kev tshawb fawb no qhia txog kev tsim qauv tsim ntawm cov catalysts tshiab rau kev hloov pauv ntawm cov organic.

Organic Synthesis Intermediate
Tshaj li catalysis, benzyldiphenylphosphine yog siv los ua ib qho reagent hauv organic synthesis rau kev npaj phosphonium ntsev ntawm quaternization nrog alkyl halides. Cov phosphonium ntsev no yog cov tseem ceeb hauv nruab nrab hauv Wittig- hom olefination cov tshuaj tiv thaiv, ua kom muaj kev tsim cov pa roj carbon - carbon ob daim ntawv cog lus nrog kev txiav txim siab stereochemistry. Lub compound yog li ua hauj lwm ob lub luag hauj lwm raws li ib tug ligand thiab ib tug hluavtaws tsev thaiv nyob rau hauv cov organic chemistry.
