Addition of methyl 2-methoxycarbonylethylphosphinate to methyl cy-clohexenonate (145 (R = Me)) gives methyl 2-methoxycarbonylethyl-2/-methoxycarbonylcyclohexylphosphinate (147), which is successively cyclized by the reaction in the presence of sodium f-pentoxide in f-pentyl alcohol and finally affords methyl l-methoyl-l,4-dioxo-2,3-4a,5,6,7,8,8a-octahydro-H5-phosphinoline-3-carboxylate (149) with the advantage of a cis ring fused bicyclic single stereoisomer formation in 45% yield (Scheme 48) [61]. 

Equimolar quantities of tellurium tetrachloride and 3,3-bis[chloromercuro]-2,4-pentanedione in refluxing 1,4-dioxane produced 3-(chloromercuro)-2,4-dioxo-3-pentyl tellurium trichloride. The brown solid (recrystallized from diethyl ether) retained two molecules of dioxane that are slowly given off on storage9. 

Borsenberger et al. (1995a) measured electron mobilities of PS doped with a series of acceptor molecules 2-r-butyl-9,10-N,N -dicyanoanthraquinone-diimine (DCAQ), 2-methy 1-2-pentyl-1,3-bis(dicyanomethylene)indane (DCMI), 3,5-dimethyl-3, 5 -diisopropyl-4,4,-diphenoquinone (DPQ-A), N,N -bis(l, 2-di-methylpropyl)-l,4,5,8-naphthalenetetracarboxylic diimide (NTDI), and 1,1-dioxo-2-(4-methylphenyl)-6-phenyl-4-(dicyanomethylidene)thiopyran (PTS). The reduction potentials are -0.22, -0.34, -0.45, -0.56, and -0.15 V, respectively. The dipole moments are between 0.30 and 4.0 Debye. In all materials, the field and temperature dependencies were described as logu oc pE1/2 and -(T0/rP)2. Figure 33 shows the results for 40% NTDI doped PS. The results...
