The compounds are prepared by reacting dichlorodisilanes of formula ClR2Si-SiR2Cl with siloxane diols of formula HO-(R2SiO)a-H, in the presence of an acid acceptor. Examples describe the preparation of octaphenyl-2,3,5,7-tetrasila - 1,4,6 - trioxacycloheptane, 2,2,3,3 - ...
Cyclic Compounds Examples Lesson Summary Frequently Asked Questions What are cyclic hydrocarbons used for? Cyclic hydrocarbons represent a type of organic compound due to the presence of carbon atoms in their structure. Cyclic hydrocarbons are used in a variety of biological compounds and in industrial...
Step-by-Step Solution:1. Definition of Alicyclic Compounds: - Alicyclic compounds are a class of organic compounds that are cyclic in structure but do not contain aromatic rings. They are characterized by ha
The preparation, characterisation, properties and applications of a wide range of organic and inorganic cyclic oligomers and polymers are described in detail, together with many examples of catenanes and rotaxanes. The importance of large cyclics in biological chemistry and molecular biology is ...

Based on the reaction partner “1”, this digest will be categorized in the following order: carbene/nitrene, alkyne/alkene, carbonyl compounds. In case of some important examples mechanistic profile is discussed briefly to show the reaction pathway. View article Three-membered Heterocycles, together...
The attention will be limited to those cases in which homogeneous metal-containing systems have been employed because they possess the highest potential for directed organic synthesis using CO2 as molecular building block. This review discusses examples of exceptional reactivity and selectivity, taking...
Chemoenzymatic cascade catalysis has emerged as a revolutionary tool for streamlining traditional retrosynthetic disconnections, creating new possibilities for the asymmetric synthesis of valuable chiral compounds. Here we construct a one-pot concurrent chemoenzymatic cascade by integrating organobismuth-catalyzed...
