Focusing on the Elements - Colors and Chemical Names (2)


Kentaro Sato
Vivid, diverse, and changeable colors of chemicals lured many of us stepping into the field of chemistry as young students. There are indeed a number of elements and compounds that display beautiful colors. Some of them are used as synthetic dyes and were a major part of the early development of chemical industry. From litmus paper to state-of–the-art bioimaging technologies, color and chemical research always go hand in hand.
So not surprisingly, there are quite a few chemicals with names derived from their colorful appearances. In this article, let us look at some of the interesting examples.

An anti-Markovnikov Hydration Reaction of Terminal Alkynes Using Ruthenium Complexes

Herzon et al. have reported the anti-Markovnikov hydration reaction of terminal alkynes using ruthenium complexes. According to their results, terminal alkynes can be directly converted to aldehydes via an anti-Markovnikov hydration reaction by using a ruthenium complex prepared from tris(acetonitrile)cyclopentadienylruthenium(II) hexafluorophosphate (1) and a bipyridyl ligand (2). This reaction proceeds under milder conditions compared to other conventional reactions using ruthenium catalysts and it shows high reactivity even with the addition of only 2 mol% of the ruthenium catalyst at room temperature. In addition, this reaction can be applied to various substances such as sterically hindered terminal alkynes, a hydroxy group or an amide group-substituted terminal alkynes and conjugated enynes. Thus, this synthetic method is expected to be used as an efficient anti-Markovnikov hydration reaction.

Chemiluminescence Reagent for the Detection of Intramitochondrial Superoxide

10,10'-Dimethyl-9,9'-biacridinium bis(monomethyl Terephthalate) (MMT), developed by Kobayashi et al., is a lucigenin derivative, which is a specific probe having green chemiluminescence to superoxide among reactive oxygen species. Since amphiphilic MMT which is less hydrophilic than lucigenin possesses cell-permeability, MMT has been applicable for the detection of intramitochondrial superoxide production. Figure 1 shows the localization of MMT in mitochondria in mouse peritoneal neutrophils.

Pentafluorophenyl column for HPLC “TCI Stella PFP”

• Analysis of Triphenylphosphine and Triphenylphosphine Oxide by TCI Stella PFP
Pentafluorophenyl column
TCI Stella PFP has the following unique interactions;
 • hydrophobic interaction
 • π-π interaction
 • dipole-dipole interaction
 • Hydrogen bond


Thus it is different separation from ODS columns.
