“…Because of the high reactivity of these functional groups, TESPIC has been used as a crosslinking reagent in various addition reactions. Recent developments of using TESPIC in assembling hybrid materials and in the synthesis of novel compounds have also been reported . The internal ester group of isocyanate in the TESPIC molecule is expected to realize hydrogen transfer reaction with some active molecules having reactive hydrogen atoms …”

Four novel magnetic nanoparticle catalysts with urea or urethane moieties are reported. The silica‐coated magnetic nanoparticles were simply functionalized via addition of 3‐(triethoxysilyl)propylisocyanate (TESPIC), amine or amino alcohol. TESPIC with dual labile functional groups was used as a suitable precursor for the synthesis of urethane‐based catalysts. The newly synthesized catalysts were fully characterized using a variety of techniques. These functionalized magnetic nanoparticles were used as reusable catalysts in the Strecker synthesis of α‐aminonitrile derivatives under solvent‐free conditions at 50 °C.

Thermolysis of Ru 3 (CO) 12 with carboxylic acids directly accessed a large variety of low valence ruthenium carbonyl complexs. Under the conditions of the reaction firstly reported by J. Lewis, 3 equivalents of acids were employed to assembly sawhorsetype dirutheniumtetra carbonyl complex. Six Ru 3 -Ru 6 ruthenium clusters were unexpectedly isolated in the reaction of Ru 3 (CO) 12 with 1 equivalent of carboxylic acids under thermal condition. The reaction of Ru 3 (CO) 12 with ten kind of carboxylic acids were systematically investigated. The reactions of Ru 3 (CO) 12 with non-coordinative carboxylic acids afforded b-H 2 Ru 4 (CO) 13 (2), Ru 6 (m 6 -C)(m-CO)(CO) 16 (3) and then to Ru 6 (m 6 -C)(m-CO)(CO) 13 (h 6 -C 6 H 5 CH 3 ) (4), respectively. The further experiments indicated that the formation of 3 was attributed to the assembly of tetraruthenium carbonyl dihydrid 2 with polymeric sawhorse diruthenium intermediate [Ru 2 (CO) 4 (OOR) 2 ] n (R = alkyl, aryl). The thermolysis of phenylpropiolic acid with Ru 3 (CO) 12 unveiled an alternative pathway to access Ru 6 skeleton. The triruthenium cluster [(m-H)Ru 3 (CO) 9 (m 3 -h 2 -(?)-C CC 6 H 5 )] (5) and butterfly tetraruthenium compound Ru 4 (CO) 12 (HC CC 6 H 5 ) (6) were identified as the key intermediates in the construction of compound 3.[a] J.
