(Chemical Equation Presented) Various alkenes were prepared from phenyl sulfides in a one-pot manner at room temperature by converting them to the corresponding S-aminosulfonium salts with O-mesitylenesulfonylhydroxylamine, followed by treatment with pota

Hydrogen transfer hydroalumination of terminal alkenes and dienes can be achieved with 1.1 equiv. of (i-Bu)3Al and catalytic amounts of Cl2Pd(PPh3)2 and other late transition metal complexes containing Co, Rh, Ni, and Pt at ambient temperature in high yields.

Medium ring size lactones can be prepared from bifunctional commercial starting compounds in high yields, using a few step sequence.Lactonisation is obtained by cyclization of the free ω-hydroxyacids or by the cyclization of ω-hydroxyacids having the hydroxy and carboxy group protected.

Like other lithio derivatives of thioacetals bearing a second anionic site, dilithio derivatives of 3,3-, 5,5-, and 6,6-bis(phenylthio) alcohols decompose at or below ambient temperature to yield products ascribable to carbenoid intermediates.The 5,5-deri

Treatment of six 1,5- and 1,6-oxosulfonium salts with potassium tert-butoxide affords an oxabicyclohexane, an oxabicycloheptane, hydrindan oxides, or a decalin oxide in 55-95percent yield.The stereoselectivity of this reaction ranges from 75percent for the formation of (1α,3α,7α)-2-oxatricyclo1,3>decane (21) to greater 99percent for (1α,2α,7α)-2-oxatricyclo1,3>decane (14) and for (1α,2α,8β)-2-oxatricyclo1,3>undecane (25).Five 1,7-oxosulfonium salts, one 1,8-salt, and one 1,11-salt and base give only elimination products.The sulfonium salt from 2-cyclopentanone (29) provides 3-methylspirodec-2-en-6-one (30) in 40percent yield.The salt from 2-cyclohexanone (32) yields 38percent of 4-methylbicycloundeca-1(7),3,5-triene (33).
