In general, the reactions of t-alkyl halides with alkali metal alkoxides and phenoxides in polar solvents give olefins (E) almost alone. However, we found a new method for the preparation of t-alkyl ethers (SN) in the reactions of t-alkyl substrates

t is a well-known result that the reactions of t-alkyl halides with alkali metal aryl oxides and alkoxides in protic solvents give olefins (E) almost exclusively. By contrast, we found a new method for the Williamson ether synthesis in the reactions

The reaction between potassium iron carbonylates (KHFe(CO)4, K2Fe(CO)4 and K2Fe2-(CO)8) and different olefin oxides has been studied. 1,2-Olefin oxides generally react with these carbonylates and carbon monoxide under an atmospheric pressure and at 3

In the reaction of cobalt hydrocarbonyl with 1-pentene at 10°C, solvents have a great effect on the distribution of the products, caproylcobalt carbonyl (I) and α-methylvalerylcobalt carbonyl (II). The I-to-II ratio is 72 : 28 in toluene, in toluen

The reaction of olefin oxide with cobalt hydrocarbonyl in the presence of inorganic (and organic) additives has been investigated. 1) The addition of relatively small amounts of various compounds of copper and silver promote the carbonylation of prop
