PerkinElmer announced that it has signed an agreement to acquire
CambridgeSoft, the latter proprietary of the popular chemistry suite
ChemOffice.

chemical giant
Dow Chemical has announced that it is to buy Philadelphia-based rival
Rohm and Haas. Pizza is paying $78 per share, a 74 percent premium, which makes the agreement worth around $15.3 billion. The change will expand Dow's presence in the
specialty chemical market. Dow plans to set up an advanced materials business unit at the Rohm and Haas headquarters in Philadelphia, and this unit will retain the Rohm and Haas name.

2-15 Chemists modeling the structure of strongly
acidic solutions have found that
hydronium ions can associate into unusual
ion pairs. Gregory A. Voth and Sergei Izvekov of the
University of Utah, in collaboration with Feng Wang of
Boston University, were examining the structure of aqueous
hydrochloric acid at concentrations of 0.43-0.85
M, and they found that the ions unexpectedly associate into pairs. See

Zincke reaction rediscovered by research groups from Japan and the U.S.A. German chemist Manfred Christl criticizes responsible scientists and publishers for doing sloppy work in a letter to the Angewandte Chemie: the chemistry presented is not new and the structure assignment incorrect.

10-30 Chemists from the
University of Delaware, Newark, in collaboration with the
University of Wisconsin-Madison, recently reported their preparation of a complex containing two chromium atoms connected by the shortest ever metal-metal bond, 1.8028 Å (0.l nm) long. It is believed to contain a
quintuple bond.

08-12 British chemical giant ICI accepts a takeover offer of £8 billion from Dutch
Akzo Nobel. Assuming approval goes through, this marks the end of a British industrial icon, known for its discovery of
polyethylene and for its
Dulux paint line.

07-16: Sustainable development: At the 2007 "C6 conference" in
Paris, the presidents of six major chemical societies pledged to "demand responsible use of resources, and ensure that the next generation of scientists protects and maintains the well-being of Earth and its inhabitants." The pact was developed by
ACS,
RSC, as well as societies representing Japan, Germany, France and the Netherlands.

01-23: Pharmaceutical giant
Pfizer announced a major restructuring plan, involving the loss of 10,000 jobs worldwide, after the failure of
Torcetrapib in clinical trials. The $7bn.
R&D budget remains intact, but in future Pfizer aims to bring in more externally sourced drug candidates.

2006-06-05 Japanese chemists have prepared and described the first ever all-carbon
persulfurane called bis(2,2'-biphenylylene) dimethylpersulfurane in which a central
sulfur atom is bonded to 4
aryl groups and two
methyl groups. In ordinary organosulfur compounds, sulfur has only two carbon neighbors. The compound is reported to be stable and moisture insensitive.

2006-04-25 The groups of
E.J. Corey (
Harvard) and
Masakatsu Shibasaki (
Tokyo) have published new syntheses of
oseltamivir (Tamiflu) bypassing the expensive and scarce
shikimic acid, the starting material in the current production method. Corey's group elected not to patent their procedure, in order to stimulate work on reducing costs and supply problems ahead of a possible
flu pandemic.
2006-03-28 Chemists in the group of A. Prasanna de Silva at
Queen's University of Belfast have designed a compound that contains three
electrolytereceptors in one small molecule. The substance (shown below) is a
molecular logic gate and is described in a paper in
JACS (online March 28, 2006), and is able to detect
Na+,
H+ and
Zn2+ in aqueous solution.
