Metathesis of P=C Bonds Catalyzed by N‐Heterocyclic Carbenes

Autor: Derek P. Gates, Zeyu Han

Publikováno v: Chemistry – A European Journal. 27:14594-14599

The catalytic metathesis of C=C bonds is a textbook reaction that has no parallel in the widely studied area of multiple bonds involving heavier p-block elements. A high-yielding P=C bond metathesis of phosphaalkenes (ArP=CPh2 , Ar=Mes, o-Tol, Ph) ha

Publikováno v: The Journal of Organic Chemistry. 85:14643-14652

The multistep synthesis and characterization of new P═C analogues of olefins from readily available starting materials is reported. Specifically, the phosphaalkenes TMOP-P═CPh2 (1a: TMOP = 2,4,6-trimethoxyphenyl) and ArF-P═CPh2 [1b: ArF = 2,6-b

Chemical- and light-induced isomerization of the P=C bond of a 1-phosphabutadiene

Autor: Henry T G Walsgrove, Philipp Dabringhaus, Derek P. Gates, Brian O. Patrick

Publikováno v: Canadian Journal of Chemistry. 98:373-378

Treatment of Mes*P=C(Si(CH3)3)Br with CH2=CHMgBr in the presence of Pd(0) affords 1-phosphabutadiene Mes*P=C(Si(CH3)3)–CH=CH2 (1) selectively as the Z isomer. Remarkably, treatment of Z-1 with n-BuLi (0.1 equiv.) resulted in quantitative formation

A Smart Phosphine–Diyne Polymer Displays 'Turn-On' Emission with a High Selectivity for Gold(I/III) Ions

Autor: Benjamin W. Rawe, Kerim Samedov, Azalea Uva, Derek P. Gates, Zeyu Han, Harvey K. MacKenzie, Henry T G Walsgrove

Publikováno v: Journal of the American Chemical Society. 142:10319-10324

A polymeric phosphine sensor is reported that exhibits bright blue fluorescence in the presence of gold(I/III) ions but is nonemissive with other metal ions. Specifically, solutions of a poly(p-arylenediethynylene phosphine) copolymer are 35 or 94 ti

A thermolytic route to a polysilyne

Autor: Kerim Samedov, Derek P. Gates, Lisa Rosenberg, Peter T. K. Lee, C Jonathan Clarke, Roman G. Belli

Publikováno v: Chemical Communications. 56:14063-14066

We report a safe and convenient method to prepare a new class of network polysilane, or polysilyne ([RSi]n). Simple thermolysis of a readily accessible linear poly(phenylsilane), [PhSiH]n, affords polysilyne [PhSi]n with concomitant evolution of mono
