A novel and efficient synthesis of pyrrolo[3,2,1-kl]phenothiazines has been developed through a Cu(I)-catalyzed tandem C-S coupling/double cyclization process. Using 2-alkynyl-6-iodoanilines and o-bromobenzenethiols as the starting materials, a wide range of pyrrolo[3,2,1-kl]phenothiazine derivatives were facilely and efficiently generated in one...

J Sep Sci. 2014 Feb;37(4):440-6. doi: 10.1002/jssc.201301183. Epub 2014 Jan 06.

In this work, a graphene composite was coated onto etched stainless-steel wire through a sol-gel technique and it was used as a solid-phase microextraction (SPME) fiber. The prepared fiber was characterized by SEM, which revealed that the fiber had...

Resonance-enhanced multiphoton ionization (REMPI) spectroscopy of bromobenzene and its perdeuterated isotopologue: Assignment of the vibrations of the S(0), S(1), and D(0)(+) states of bromobenzene and the S(0) and D(0)(+) states of iodobenzene.

We report vibrationally resolved spectra of the S1←S0 transition of bromobenzene using resonance-enhanced multiphoton ionization spectroscopy. We study bromobenzene-h5 as well as its perdeuterated isotopologue, bromobenzene-d5. The form of the vibrational modes between the isotopologues and also between the...

Aggregation and Alkylation of the Cesium Enolate of 2-p-Biphenylylcyclohexanone(1).

The Journal of organic chemistry

Streitwieser A, Wang DZ, Stratakis M.
PMID: 11674562
J Org Chem. 1999 Jun 25;64(13):4860-4864. doi: 10.1021/jo990251u.

The cesium enolate of 2-biphenylylcyclohexanone (CsBPCH), generated by deprotonation of 2-biphenylylcyclohexanone with diphenylmethylcesium, is shown to be a mixture of monomer and dimer in THF, with a dimerization constant of 1.9 x 10(3) M(-)(1). The ion pair acidity corresponds...

Dimethylformamide as a carbon monoxide source in fast palladium-catalyzed aminocarbonylations of aryl bromides.

The Journal of organic chemistry

Wan Y, Alterman M, Larhed M, Hallberg A.
PMID: 12182668
J Org Chem. 2002 Aug 23;67(17):6232-5. doi: 10.1021/jo025965a.

Dimethylformamide (DMF) acts as an efficient source of carbon monoxide and dimethylamine in the palladium-catalyzed aminocarbonylation (Heck carbonylation) of p-tolyl bromide to provide the dimethylamide. Addition of amines to the reaction mixture in excess delivers the corresponding aryl amides...

Cationic hafnium silyl complexes and their enhanced reactivity in sigma-bond metathesis processes with Si-H and C-H bonds.

Reaction of the mixed-ring silyl methyl complex CpCp*Hf[Si(SiMe3)3]Me (4) with B(C6F5)3 in bromobenzene-d5 yielded the zwitterionic hafnium silyl complex [CpCpHfSi(SiMe3)3][MeB(C6F5)3] (7), which is stable for at least 12 h in solution. Addition of PhSiH3 to 7 rapidly produced HSi(SiMe3)3,...
