In organic chemistry, the Myers deoxygenation reaction is an organic redox reaction that reduces an alcohol into an alkyl position by way of an arenesulfonyl hydrazine as a key intermediate. This name reaction is one of four discovered by Andrew Myers that are named after him; this reaction and the Myers allene synthesis reaction involve the ...
In organic chemistry, the Myers allene synthesis is a chemical reaction that converts a propargyl alcohol into an allene by way of an arenesulfonyl hydrazine as a key intermediate. [1] This name reaction is one of two discovered by Andrew Myers that are named after him; both this reaction and the Myers deoxygenation reaction involve the same ...
In stereochemistry, a chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. [ 1 ] [ 2 ] The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions.
=:. ^ (^) for all unit vectors ^ For the extended constructions one or more additional terms are included for interface free energies, for instance the marked in purple with dashes in the figure. The dashed interface is included which may be a solid interface for the Winterbottom case, two interfaces for Summertop and or one, two or three twin ...
Ring expansion and ring contraction reactions expand or contract rings, usually in organic chemistry. The term usually refers to reactions involve making and breaking C-C bonds, [1] Diverse mechanisms lead to these kinds of reactions. The bond migration step of the pinacol type rearrangement

Ring-closing metathesis (RCM) is a widely used variation of olefin metathesis in organic chemistry for the synthesis of various unsaturated rings via the intramolecular metathesis of two terminal alkenes, which forms the cycloalkene as the E-or Z-isomers and volatile ethylene.
