The first attempted laboratory synthesis was made in 1924 by German chemist Hans Meerwein using the reaction of formaldehyde with diethyl malonate in the presence of piperidine. Instead of adamantane, Meerwein obtained 1,3,5,7-tetracarbomethoxybicyclo[3.3.1]nonane-2,6-dione: this compound, later named Meerwein's ester, was used in the synthesis ...

Most 1-bromoalkanes are prepared by free-radical addition of hydrogen bromide to the 1-alkene.These conditions lead to anti-Markovnikov addition, giving the 1-bromo derivative.
Eon Productions, which now holds the adaptation rights to all of Fleming's Bond novels, made all but two films in the film series. [1] [2] In 1961, producers Albert R. Broccoli and Harry Saltzman purchased the filming rights to Fleming's novels. [3] They founded Eon Productions and, with financial backing by United Artists, produced Dr.
The attometre (SI symbol: am) is a unit of length in the metric system equal to 10 −18 metres. To help compare different orders of magnitude, this section lists lengths between 10 −18 m and 10 −17 m (1 am and 10 am). 1 am – sensitivity of the LIGO detector for gravitational waves [citation needed]
SOD1 binds copper and zinc ions and is one of three superoxide dismutases responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic and mitochondrial intermembrane space protein, acting as a homodimer to convert naturally occurring, but harmful, superoxide radicals to molecular oxygen and hydrogen peroxide.
