The synthesis of alkenones [R 3-C(O)C(R2)C(R1)-OR], where R/R 1/R2/R3 = Et/H/H/Ph, t-Bu/H/H/Ph, Me/-(CH 2)4/Ph, Me/-(CH2)4/Me] from the reaction of enol ethers with benzoyl chloride or acetyl chloride, in ionic liquid [BMIM][BF4], is also reported. Last products are described for the first time.

scheme or table, p. 659 - 662 (2011/06/21)
A series of β-ketoamine ligands with different steric and electronic substituents on the backbone and with aniline moieties have been synthesized and characterized. In the presence of PdCl2, catalytic studies indicated that they are effective l
Cyclo-ruthenated and -platinated complexes bearing phosphonate substituents
Wadman, Sipke H.,Tooke, Duncan M.,Spek, Anthony L.,van Klink, Gerard P.M.,van Koten, Gerard
experimental part, p. 1701 - 1706 (2010/08/22)
Two new, potentially cyclometalating terdentate ligands bearing phosphonate substituents, Et2O3P-N^C(H)^N (5) and Et2O3P-C(H)^N^N (7), have been prepared. The corresponding ruthenium complexes, [1]+ and [2]+, respectively, were obtained by reaction with [RuCl3(tpy)]. Complexes [1]+ and [2]+ display electronic properties characteristic for cyclometalated ruthenium complexes. The platinum complex [3], of N^C(H)^N ligand 5, was also prepared and is highly phosphorescent in solution. In general, the phosphonate group electronically behaves equivalent to a carboxylate moiety.
Synthesis of functionalized salicylates by formal [3+3] cyclocondensation of 1,3-bis(silyloxy)buta-1,3-dienes with 3-alkoxy-2-en-1-ones

experimental part, p. 2236 - 2248 (2009/12/26)
The formal [3+3] cyclization of 1,3-bis(silyloxy)buta-1,3-dienes with 1-aryl-3-ethoxyprop-2-en-1-ones, available by Heck reaction of benzoyl chlorides with ethyl vinyl ether, afforded a variety of 6-arylsalicylates. The reaction of the products with conce
Synthesis of functionalized biaryls based on a heck cross-coupling-[3+3] cyclization strategy

experimental part, p. 963 - 966 (2009/04/04)
6-Arylsalicylates were regioselectively prepared by formal [3+3] cyclization of 1,3-bis(silyloxy)-1,3-butadienes with 1-aryl-3-ethoxyprop-2-en-1- ones which are available by Heck reaction of benzoyl chlorides with ethylvinyl ether. In this context, the first [3+3] cyclizations of brominated substrates are reported. Georg Thieme Verlag Stuttgart.
