The application of CCl4, C6H12, EtOAc, and Me2CO as solvents for biphasic systems has been compared for oxidative cleavage of alkenes and alkynes by RuO4 to carboxylic acids, using the RuCl3 · nH2O–IO(OH)5 reagent for which an improved procedure is described. Cyclohexane is an ...
A terminal alkyne can be synthesized from a 1,2-dihalo compound. We recall that this starting material can be synthesized in an addition reaction of a halogen to a monosubstituted (terminal) alkene. For example, adding chlorine to 1-hexene yields 1,2-dichlorohexane. The doubledehydrohalogenatio...

2c, alkene p-complexation between C and a Lewis acidic Rh(I) centre would promote intramolecular nucleophilic attack by the N–H imine moiety in stereospecific 6-endo-trig fashion to give metal alkyl intermediate F. With the stereochemistry of C–N bond formation determined by such anti-amino...
7.08.3.1.3 δ to the heteroatom Palladium-catalyzed oxidative cyclization of aryl homoallyl ethers affords 4-methyl-2H-chromenes in moderate yield. The reaction is proposed to proceed via activation of the alkene by coordination to Pd(ii) followed by intramolecular nucleophilic attack by the arene...
