From alkenes using DPH [ edit ] Aziridines are obtained by treating a mono-, di-, tri- or tetra-substituted alkene (olefin) with O -(2,4-dinitrophenyl)hydroxylamine [ de ] (DPH) in the presence of rhodium catalysts:
Crabtree’s catalyst is effective for the hydrogenations of mono-, di-, tri-, and tetra-substituted substrates. Whereas Wilkinson’s catalyst and the Schrock–Osborn catalyst do not catalyze the hydrogenation of a tetrasubstituted olefin, Crabtree’s catalyst does so to at high turnover frequencies (table). [2] [5]
Numbering of the various substituents and bonds with their locants. If there is more than one of the same type of substituent/double bond, a prefix is added showing how many there are (di – 2, tri – 3, tetra – 4, then as for the number of carbons below with 'a' added at the end)
If there is more than one of the same alkyl group attached to a chain, then the prefixes are used on the alkyl groups to indicate multiples (i.e., di, tri, tetra, etc.) This compound is known as 2,3,3-trimethylpentane. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3.
In this case the number n (which is between 1 and 4) is indicated by a multiplier prefix (mono-, di-, tri-, tetra-, penta-, or hexa-). The unqualified term "hydroxybenzoquinone" usually means a derivative of 1,4-benzoquinone. Other hydroxy- compounds can be derived from the other isomer, namely 1,2-benzoquinone or ortho-benzoquinone.
Pnictogen-substituted tetrahedranes are pnictogen-containing analogues of tetrahedranes with the formula R x C x Pn 4-x (Pn = N, P, As, Sb, Bi). [1] Computational work has indicated that the incorporation of pnictogens to the tetrahedral core alleviates the ring strain of tetrahedrane. [ 2 ]
In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. [1] ( In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, [2] though certain ...
