Chemoselective Claisen-Schmidt bis-substitutional condensation catalyzed by an alkoxy-bridged dinuclear Ti(IV) cluster

The highly efficient and chemoselective alpha,alpha?-bis-substitution of alkanones is important in organic synthesis. Herein, a dimeric titanium cluster, Ti2Cl2(OPri)6¡¤2HOPri (Ti2), is used in the Claisen-Schmidt condensation reaction, for the selectively activation of symmetrical ketones containing alpha,alpha?-methylene groups and production of alpha,alpha?-bis-substituted alkanones in high efficiency and chemoselectivity. The high efficiency and chemoselectivity can be extended to a variety of typical alkanones and aromatic aldehydes. Both of the oxo-bridged dimeric motif of Ti2 and the ionic Ti-Cl bond are responsible for the high efficiency and chemoselectivity.

A diene-transmissive Diels-Alder reaction involving inverse electron-demand hetero-Diels-Alder cycloaddition of cross-conjugated azatrienes

The initial inverse electron-demand hetero-Diels-Alder reaction of N-sulfonyldivinylmethanimine with electron-rich dienophiles (ethyl vinyl ether and ethyl vinyl sulfide) affords [4+2] cycloadducts with high endo selectivity. The monocycloadducts then undergo a second Diels-Alder reaction on the newly formed diene unit with electron-deficient dienophiles (tetracyanoethylene, 4-phenyl-1,2,4-triazoline-3,5-dione, and N-phenylmaleimide) to give highly stereoselectively the crossed biscycloadducts, hexa- and octahydroquinolines, and octahydropyridopyridazines.

Bridging Coordination of Vinylarenes to Pd3- or Pd4 Cluster Sites

Though the M3- or M4 face of palladium clusters may serve as the active binding site of substrates, it has been difficult to elucidate their substrate binding modes in solution. Here, it was proved that a soluble Pd3- or Pd4 sheet cluster accommodates vinylarenes at its bridging coordination site in an unusual mode in palladium chemistry; that is, for the former, the coordination of the arene moiety precedes that of olefin moiety; for the latter, vinylarene coordinates to a distorted Pd4 sheet through oxidative pi-addition of its styrene moiety.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1,5-Diphenylpenta-1,4-dien-3-one, you can also check out more blogs about538-58-9
