Magnesium, organo- compounds reactions with

Coupling of acetylenes and halides, copper-promoted, 50,100 Cuprous chloride, reaction with an organo-magnesium compound, 50,98... 

In its action on organo-magnesium compounds,3 sulphur tetrachloride behaves as if it consists only of sulphur dichloride and chlorine, and its reactions with sulphur trioxide (see before) appear to be capable of a similar interpretation in these cases it is indeed possible that sulphur dichloride and chlorine, present as products of dissociation, are the actual agents in the chemical change. 

Aminomethylotion. The reagent reacts with Grignard reagents to form N,N-bis(trimethylsilyl)amines in 60-90% yield (equation I). A similar reaction with organo-lithium compounds requires added magnesium biomide for satisfactory yields. ... 

Organo Vinyl Tellurium (from Vinyl Tellurium Iodides) A solution of the vinyl tellurium iodide, prepared by addition of 0.25 g (1.0 mmol) iodine in benzene to the divinyl ditelluride (1.0 mmol) in 5 ml tetrahydrofuran at 0° under nitrogen, is added dropwise to a solution of the organo magnesium bromide in 10 m/ tetrahydrofuran at 0°. The mixture is stirred at 20° for 1 h, hydrolyzed with a saturated aqueous solution of ammonium chloride, extracted with diethyl ether, the extract dried with magnesium sulfate and evaporated. The product is chromatographed on silica gel with petroleum ether (30-60°)/ethyl acetate (9 1) as eluent. The following compounds were prepared in this manner (yields in parentheses are for the reactions with vinyl tellurium iodides) ... 

Lead salts of other inorganic and of organic acids may replace the lead chloride, as also may lead oxide or sulfide, and these may be brought into reaction with organo-lithium, -magnesium, -zinc, or -aluminum compounds methods for obtaining tetraethyllead have been studied in particular detail.465... 

Reaction with Organometallic Compounds. Organo-magnesium (eq 4), lithium, and other main group metals readily undergo ligand transfer with PCI3 to form mono-, di-, or trialkyl(aryl) phosphines. A subclass of reactions include Aluminum Chloride-assisted transformations to form phosphetanes (eq 5). ...
