In inorganic chemistry, the cis effect is defined as the labilization (or destabilization) of CO ligands that are cis to other ligands. CO is a well-known strong pi-accepting ligand in organometallic chemistry that will labilize in the cis position when adjacent to ligands due to steric and electronic effects.
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
For a nondissociative pathway, reductive elimination occurs from the four-coordinate system to afford a two-coordinate complex. If the eliminating ligands are trans to each other, the complex must first undergo a trans to cis isomerization before eliminating. In an associative mechanism, a ligand must initially associate with the four ...
Contact image sensors (CIS) are image sensors used in flatbed scanners almost in direct contact with the object to be scanned. Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor.
Because there is a single transition state, and all modes of attack are suprafacial, stereochemistry in this reaction is retained. R 4 and R 5 are cis in the dienophile, and syn in the product. Conversely, R 3 and R 5 are trans in the dienophile, and anti in the product.
The postgame message of “sticking together” from Matt Eberflus following the Chicago Bears' Thanksgiving Day loss to the Detroit Lions reportedly did not go over well with members of the team.
A Georgia man was arrested Monday in the 1985 murder of two people at a church, after the original suspect spent two decades in prison.
An example of its use is in the synthesis of leukotriene A methyl ester. [ 20 ] [ 21 ] The first step uses a stabilised ylide, where the carbonyl group is conjugated with the ylide preventing self condensation, although unexpectedly this gives mainly the cis product.
