The preparation and reactivity of organosamarium ate complexes have also been described. By addition of methyllithium to samarium trichloride in EtiO in the presence of TMEDA, [Li(TMEDA)]3[Sm(Me)6] can be isolated in 48% yield as a crystalline solid. This complex is extremely... 

SiBr3[g] SILICON TRIBROMIDE (GAS) 1486 SmCI3 SAMARIUM TRICHLORIDE 1534... 

Tris(indenyl) complexes of. some rare earths were prepared by Tsutsui and Gysling (1968,1969) by the reaction of the metal trichlorides with the sodium salt of indene. They are isolated as tetrahydrofuran adducts. The solvent-free tris(indenyl) samarium has been made by the interaction of samarium trichloride with bis(inde-...

Samarium trichloride catalyses the condensation of allylic alcohols to form symmetrical ethers in dichloroethane and unsymmetrical... 

In his first publication in this area, Luche found samarium trichloride and CCTium trichloride (hydrated forms) to be especially effective in the selective conversion of a,j8-unsaturated ketones to allyhc alcohols (Luche, 1978), even in the case of 2-cyclopentenone, which tends to undergo 1,4-addition (essentially 100% reduction was observed with all reagent systems). 

TABLE 45 Mass spectrum coefficients of samarium trichloride, data from Chervonnyi et al. (1974)... 

One possible reason for such the discrepancy between the Pm/Pd values found from the semilogarithmic representations and mass spectral data is that the evaporation of the samples is incongruent. This is demonstrated by measuring the pressures of the saturated vapor over samarium trichloride (Pogrebnoi et al., 2001) and terbium trichloride (Khasanshin et al., 1999).
