Among theorganometallic compoundsof magnesium are the importantGrignard reagents, composed of an organicgroup(e.g., alkyls and aryls), ahalogenatomother thanfluorine, and magnesium. These are used in the production of many other kinds of organic and organometallic compounds. ...
Fast-Atom Bombardment Mass Spectrometry and Related Techniques This chapter discusses the fast-atom bombardment mass spectrometry and related techniques. Mass spectrometry has become a very important tool for the inorganic chemist, having been extensively applied particularly in the fields of organo... JM...
barium has anoxidation stateof +2. The Ba2+ionmay be precipitated from solution by the addition ofcarbonate(CO32−), sulfate (SO42−), chromate (CrO42−), or phosphate (PO43−)anions. All soluble bariumcompoundsare toxic tomammals, probably by interfering with the functioning ofpotass...
etc. On the other hand, the term N-atom containing compounds seems to be too broad, not focused enough [4]. An assembly of more special N-atom containing compounds, isolated by us over the years, is depicted in Figure 1. Figure 1. An assembly of unique marine alkaloids isolated by us...

stage 1-8 as central atom; X = a mono- or polydentate, charged or uncharged ligand attached to the central atom; L = a monocarbene of formula (IIA) or (IIB) or a dicarbene of formula (IIIA) or (IIIB), also attached to the central atom: R<1-6> = 1-7C (sulpho)alkyl, 5-...
Piperidine is widely used as an excellent base for quantitative deprotection of the Fmoc group from peptides in solid-phase peptide synthesis. Pyridines (azabenzenes) are six-membered aromatic heterocycles with one nitrogen atom in the ring. Electrophilic substitution with pyridine takes place under ...
Organosulfur compound - Sulfoxides, Sulfones, Polyvalent: Two major groups of organosulfur compounds that have no counterparts among organic oxygen compounds are the sulfoxides and sulfones. If the bonding in these compounds is represented with doubly bo
