Synthesis of 4-alkoxy-1,1-dichloro-3-alken-2-ones [CHCl2C(O) C(R2)C(R1)-OR, where R, R1, R2 = Et, H, H; Me, Me, H; Et, H, Me; Me, -(CH2)2-; Me, -(CH 2)3-; Et, Et, H; Et, Bu, H; Et, i-Pr, H; Et, i-Bu, H; Me, Ph, H; Me, thien-2-yl, H] from acylation of enol ethers and acetals with dichloroacetyl chloride, in ionic liquid ([BMIM][BF4] or [BMIM][PF6]) is reported. 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.
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 biaryls based on a heck cross-coupling-[3+3] cyclization strategy
Mro?, Gerson,Reinke, Helmut,Langer, Peter
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.
