Mechanism of Formation of Grignard Reagents. Rate of Reaction of Cyclopentyl Bromide with a Rotating Disk of Magnesium
Careful studies of the dependence of the rate of reaction (k) of cyclopentyl bromide in diethyl ether with the surface of a rotating magnesium disk as a function of the angular velocity (w) of the disk confirm the relation k a w1I2 expected for a mass-transfer limited reaction. More limited studies also indicate that the variations in this rate with other parameters are compatible with those ex...
متن کاملDi-Grignard reagents and metallacycles
Aliphatic ,w-dibromides can be converted to the corresponding c,w-di—Grignard reagents; for those members carrying less than four carbon atoms between the functions, special procedures are required. The synthesis, structure and applications of the di-Grignard reagents are discussed; particular emphasis is placed on the structures of the corresponding cyclic dialkylmagnesiums, and on the use of ...
متن کاملSingle electron transfer-induced cross-coupling reaction of alkenyl halides with aryl Grignard reagents.
Alkenyl halides were found to undergo coupling with aryl Grignard reagents to give the corresponding styrene derivatives in a stereo-retained manner. The cross-coupling reaction is considered to proceed through a single electron transfer mechanism.
متن کاملAn unusual reaction of α-alkoxyphosphonium salts with Grignard reagents under an O2 atmosphere.
An unusual and novel reaction of α-alkoxyphosphonium salts, generated from O,O-acetals and Ph(3)P, with Grignard reagents under an O(2) atmosphere afforded alcohols in moderate to high yields. It was clarified by isotopic labelling experiments that the reaction proceeded via a novel radical pathway.
متن کاملArsenous chloride-free synthesis of cyclic tertiary organoarsines from arylarsine oxides and di-Grignard reagents
The growing importance of triarylarsines as ligands for transition metal catalysis has sparked recent interest in new synthetic routes to tertiary arsines that avoid hazardous arsenous chloride reagents. However, safer methods for the synthesis of lesser explored arsine heterocycles, especially those containing As-C(sp3) bonds, remain lacking. We demonstrate for the first time that bench stable...
