Carboranes are a notable example of heteroboranes. [2] [3] The essence, these rules emphasize delocalized, multi-centered bonding for B-B, C-C, and B-C interactions. Structurally, they can be considered to be related to the icosahedral (I h) [B 12 H 12] 2− via formal replacement of two of its BH − fragments with CH.
A borane is a compound with the formula BR x H y although examples include multi-boron derivatives. A large family of boron hydride clusters is also known. In addition to some applications in organic chemistry , the boranes have attracted much attention as they exhibit structures and bonding that differs strongly from the patterns seen in ...
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
Borane adducts are widely used in organic synthesis for hydroboration, where BH 3 adds across the C=C bond in alkenes to give trialkylboranes: [13] (THF)BH 3 + 3 CH 2 =CHR → B(CH 2 CH 2 R) 3 + THF. This reaction is regioselective. [14] Other borane derivatives can be used to give even higher regioselectivity. [15]
Organosulfur chemistry is the study of the properties and synthesis of organosulfur compounds, which are organic compounds that contain sulfur. [1] They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.g., saccharin.
Examples of Lewis dot diagrams used to represent electrons in the chemical bonds between atoms, here showing carbon (C), hydrogen (H), and oxygen (O). Lewis diagrams were developed in 1916 by Gilbert N. Lewis to describe chemical bonding and are still widely used today. Each line segment or pair of dots represents a pair of electrons.
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction.. In the past, derivative also meant a compound that can be imagined to arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, [1] but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity.
Boranes can function as ligands in coordination compounds. [11] Hapticities of η 1 to η 6 have been found, with electron donation involving bridging H atoms or donation from B-B bonds. For example, nido-B 6 H 10 can replace ethene in Zeise's salt to produce trans-Pt(η 2-B 6 H 10)Cl 2. [11] They can also act as Lewis acids, with concomitant ...
