The beginning of the chemistry of organoboron compounds dates back to 1859 when Frankland discovered triethylborane,. Et3B. While the subsequent availability of Grignard reagents provided facile access to organoboranes, a major breakthrough was the discovery of the hydroboration of alkenes as a convenient entry
Organoborane Chemistry deals with the chemistry of organoboranes, with emphasis on compounds containing a carbon-boron bond. The structure and physical properties of organoboranes are discussed, along with the reactions of three-coordinate and four-coordinate organoboranes, organodiboranes, and other
various hydroborating agents made a vast array of organoboranes readily available. Organoboranes tolerate many functional groups and are often formed in a stereosnecific manner. The boron atom in these organoboranes can be readily substituted with a variety of functional qroups to give organic compounds under mild
Synthetic routes to organoboranes have largely involved use of organometallic compounds' and of olefin-hydride additions.2" It is the purpose of this article to describe a new and general approach to several classes of organoboranes. This approach is based on aluminum metal as a reactant. In summation, these class
?Carbonylation. • reaction of organoboranes with carbon monoxide. [(–):C?O:(+) ], which is an ylide, gives rise to. 3 possible rearrangements. • Depending on reaction conditions, single, double, and triple migrations of groups may occur leading, after appropriate workup, to a variety of aldehydes and ketones as well as.
Hydroboration refers to the addition of a hydrogen-boron bond to an unsaturated system such as alkene or alkyne resulting in the formation of organoboranes which can be converted to other products via subsequent transformations. This reaction was first explored by H. C. Brown and co- workers during 1950s. Alkenes
Finally, I decided to open up a new field in synthetic methodology employing organoboron compounds. The facile addition of a boron-hydrogen moiety to carbon-carbon multiple bonds of unsaturated organic derivatives gives organoboranes. This hydroboration has various characteristic properties. The reaction is very rapid
October 14, 1966,. Title REACTIONS OF ORGANOBORANES. Abstract approved. Redacted for Privacy. (Major professor). An examination was made of some reactions involving a trans- fer of carbon from boron to carbon. In the case of the reaction of a C n alkylorganoborane with dichlorocarbene the intermediate was a Cn.
