The reactivity of molybdenum pentachloride with ethers: routes to the synthesis of Mo(IV)Cl4 adducts, Mo(V) chlorido-alkoxides and Mo(V) oxydo-chlorides.

Fabio Marchetti et al.

Dalton transactions (Cambridge, England : 2003), 42(42), 15226-15234 (2013-09-06)

The reactivity of molybdenum pentachloride, 1, with a selection of mono- and diethers was investigated at room temperature in a non-coordinating solvent (dichloromethane). The Mo(IV) complex MoCl4(OMe2)2, 2, was obtained in 75% yield by the reaction of 1 with an

Mei Sun et al.

Environmental science & technology, 50(5), 2246-2254 (2016-02-02)

Recent U.S. Environmental Protection Agency data show that 1,4-dioxane is frequently detected in U.S. drinking water derived from both groundwater and surface water. 1,4-Dioxane is a likely human carcinogen, and an excess 10(-6) cancer risk is associated with a drinking

One-step synthesis of nitrogen-containing medium-sized rings via α-imino diazo intermediates.

Florian Medina et al.

Organic letters, 16(12), 3232-3235 (2014-06-03)

Eight- and 9-membered dioxazocines and dioxazonines are readily synthesized starting from N-sulfonyl-1,2,3-triazoles in a single-step procedure. A perfect regioselectivity and generally good yields (up to 92%) are obtained under dirhodium catalysis using 1,3-dioxolane and 1,3-dioxane as solvents and reagents.
