Phosphine-catalyzed dearomatizing [3+2] annulations of isoquinolinium methylides with allenes.

A phosphine-catalyzed dearomatizing [3+2] annulation of isoquinolinium methylides with allenoates or allenones yields highly functionalized pyrroloisoquinolines with high regioselectivity and in viable yields.

Efficient 2-sulfolmethyl quinoline formation from 2-methylquinolines and sodium sulfinates under transition-metal free conditions.

An efficient procedure for 2-sulfolmethyl quinoline preparation from 2-methylquinolines and sodium sulfinates under transition-metal free conditions is described. Halogen functional groups were well tolerated to give the corresponding products in good to high yields.

Green and Efficient One-Pot Synthesis of 2-Amino-3-phenylsulphonyl-4H-chromenes under Solvent-Free Conditions

A green and convenient method for the synthesis of 2-amino-3-phenylsulphonyl-4H-chromenes by a one-pot three-component condensation of 1-naphthol, phenylsulphonylacetonitrile and aromatic aldehydes under solvent-free conditions using potassium phosphate tribasic trihydrate as an efficient catalyst is described. The reaction of 1-naphthol with phenylsulphonylacetonitrile and various aromatic...

Homometallic UO2(2+) diphosphonates assembled under ambient and hydrothermal conditions.

Four uranyl methylenediphosphonates have been synthesized from reactions of uranyl nitrate and methylenediphosphonate in water. Three of the compounds, (1) (UO(2))[CH(2)(PO(3)H)(2)](H(2)O) x 2 H(2)O, (2) (UO(2))[CH(2)(PO(3)H)(2)](H(2)O) x 4 H(2)O, and (3) (UO(2))[O(3)PCH(2)PO(3)H](H(2)O) x 3 H(2)O x NH(4), have been synthesized under ambient conditions whereas compound 4, (UO(2))[CH(2)(PO(3)H)(...
