In organic chemistry, carbonyl reduction is the conversion of any carbonyl group, usually to an alcohol. It is a common transformation that is practiced in many ways. [ 1 ] Ketones , aldehydes , carboxylic acids , esters , amides , and acid halides - some of the most pervasive functional groups , -comprise carbonyl compounds.
Organoborane activation with hydroxide or alkoxide and treatment with X 2 yields haloalkanes. With excess base, two of the three alkyl groups attached to the boron atom may convert to halide, but disiamylborane permits only halogenation of the hydroborated olefin: [ 46 ]
On 9 November 1971, Gen John D. Ryan, Air Force Chief of Staff, approved the establishment of the Community College of the Air Force. The Secretary of the Air Force approved the plan 25 January 1972, and the college was officially established on 1 April 1972, at Randolph AFB, TX. [3] Until the mid-1970s, the CCAF offered only certificate programs.
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
The Air War College (AWC) is the senior Professional Military Education (PME) school of the U.S. Air Force. A part of the United States Air Force's Air University, AWC emphasizes the employment of air, space, and cyberspace in joint operations. [1] Headquartered at Maxwell Air Force Base in Montgomery, Alabama, its higher headquarters is the ...
After World War II, with the establishment of an independent U.S. Air Force in 1947, and as the service grew and developed, the requirements and expectations of the renamed Air Command and Staff School evolved to fulfill the service's educational needs. In 1952, Major Jeanne M. Holm became the first woman to attend the Air Command and Staff ...
The Air Force also supplied several PT-17 Stearmans and a few P-40 Warhawks. Spartan furnished instructors, training sites and facilities, aircraft maintenance, quarters, and mess halls. [4] Students from the Royal Air Force entered the school on June 7, 1941. The U. S. Army Air Forces officially designated Spartan as a British Refresher School ...
