Allylsilanes and Vinylsilanes from Silylcupration of Carbon−Carbon Multiple Bonds:  Scope and Synthetic Applications

Francisco J. Pulido, Asunción Barbero
Acc. Chem. Res. | 2004 | 10.1021/ar0400490

Silylcupration of multiple bonds (allenes, acetylenes, dienes, and styrenes) has become one of the most efficient procedures for the synthesis of vinyl- and allylsilanes. These substrates are useful building blocks in organic synthesis since they undergo a...

Double Helix-to-Double Helix Transformation, Using Platinum(II) Acetylide Complexes as Surrogate Linkers

Yoshie Tanaka, Yoshio Furusho, Eiji Yashima
Org. Lett. | 2006 | 10.1021/ol0608294

We describe novel optically active double helices consisting of complementary strands stabilized by amidinium−carboxylate salt bridges. The m-terphenyl groups of each strand are joined by trans-Pt(II) acetylide complexes with pendant PPh 3 ligands as the...

N-Heterocyclic Carbene-Catalyzed Silyl Enol Ether Formation†

Nathan K. Yee, Chris H. Senanayake, Jonathan T. Reeves, Daniel R. Fandrick, Zhulin Tan, Jinhua J. Song
Org. Lett. | 2008 | 10.1021/ol703025b

N-Heterocyclic carbenes (NHCs) were found to catalyze the silyl transfer from trialkylsilyl ketene acetals to ketones. In the presence of a catalytic amount of NHC 3 (IAd, 0.1 to 5 mol %), a series of enolizable ketones as well as cyclohexanecarboxaldehyde...

Ni(II)/Zn Catalyzed Reductive Coupling of Aryl Halides with Diphenylphosphine Oxide in Water

Xiaomei Hu, Xinghua Zhang, Huizhi Liu, Jun Zhu, Guo Tang, Yufen Zhao
Org. Lett. | 2011 | 10.1021/ol201141m

P-Arylation in water has been developed via cross-coupling of aryl halides with diphenylphosphine oxide (Ph 2 P(O)H) and (R P )-(−)-menthyl benzylphosphinate catalyzed by NiCl 2 ·6H 2 O/Zn under relatively mild conditions.

Ruthenium-Catalyzed Hydrosilylation of 1-Alkynes with Novel Regioselectivity

Yukio Kawanami, Yoshiya Sonoda, Keiji Yamamoto, Takashi Mori
Org. Lett. | 2002 | 10.1021/ol026089q

A ruthenium catalyst precursor bearing a bulky and electron-donating pentamethylcyclopentadienyl (Cp*) ligand, typically Cp*RuH 3 (PPh 3 ), mediates hydrosilylation of several 1-alkynes with novel regioselectivity to give preferentially 2-silyl-1-alkenes.

A Modular Rearrangement Approach toward Medicinally Relevant Phosphinic Structures

Dimitris Georgiadis, Vincent Dive, Vassilis Rogakos, Athanasios Yiotakis
Org. Lett. | 2009 | 10.1021/ol902004p

An unprecedented coupling of a P−C and a C−C bond-forming event in a practical operation was developed to access medicinally relevant phosphinic structures. The strategy relies on an Ireland−Claisen rearrangement triggered by the phospha-Michael addition of...

One-Pot Synthesis of Arylboronic Acids and Aryl Trifluoroborates by Ir-Catalyzed Borylation of Arenes

John F. Hartwig, Jaclyn M. Murphy, C. Christoph Tzschucke
Org. Lett. | 2007 | 10.1021/ol062903o

The synthesis of arylboronic acids and aryl trifluoroborates in a one-pot sequence by Ir-catalyzed borylation of arenes is reported. To prepare the arylboronic acids, the Ir-catalyzed borylation is followed by oxidative cleavage of the boronic ester with NaIO ...

Seijiro Matsubara, Takuya Kurahashi, Takuya Ozawa
Org. Lett. | 2011 | 10.1021/ol202283d

The dehydrogenative cycloaddition of dieneynes, which possess a diene in the form of a styrene moiety and a dienophile in the form of an alkyne moiety, produces naphthalene derivatives when heated. It was found that a key requirement of this process is the...
