DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 Three organometallic complexes [C6H4-p-(CO2CH2C2H-m)2][Co2(CO)6]2 (1), [C6H4-p-(CO2CH2C2H)2][RuCo2(CO)9]2 (2) and [(HC2CH2OCO)C6H4-p-(CO2CH2C2H-m)][Mo2Cp2(CO)4] (3) have been prepd. from the reactions of dipropargyl terephthalate with Co2(CO)8, Mo2Cp2(CO)4 and RuCo2(CO)11. From their 1H NMR spectra, it is found that the deshielding effect of metal species on terminal alkyne follows RuCo2(CO)9 > Co2(CO)6 > Mo2(CO)4Cp2. The single-crystal diffraction of compd. 1 was undertaken with the data: triclinic, P~1, a = 8.139(2)?, b = 8.808(3)?, c = 11.343(3)?, b = 96.260(6)°, V = 773.4(4)°3, Z = 1, Dc = 1.748g × cm-3, R = 0.0513, wR = 0.1266.

CLASS: IC: B01J031-40; C07C029-16; C07C029-80. ICA: C07C031-02. APPLICATION: JP 82-62374 16 Apr 1982. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23 Catalysts comprising Co compds. and tertiary phosphines, for hydroformylation and hydrogenation of olefins or olefin-aldehyde mixts., are sepd. from the reaction mixt. by extractive distn. with a solvent b. higher than the product alcs. but lower than the tertiary phosphines. Thus, propylene dimer [16813-72-2] was hydroformylated in the presence of dicobalt octacarbonyl (I) [10210-68-1] to give a mixt. contg. 83.5% heptanal [111-71-7], 1 kg of which was mixed with 11.6 g I and 50 g tri-n-octylphosphine [4731-53-7] in an autoclave, then treated with 2:1 H/CO at 190-200° and 70 kg/cm2 (gage) for 2 h to give a mixt. contg. 89.2% product heptanol [53535-33-4] and 5.6% catalysts. This mixt. 25322-68-3 and 53535-33-4 are also in the experiment. (100 g) was combined with 35 g tetraethylene glycol (II) [112-60-7], evacuated to 5 mm Hg, and heated to obtain 94.2 g distillate (94.7% heptanol) at 70-180°, and 9.3 g bottom residue contg. 60.2% catalysts. The catalysts were not decompd. during distn.; they could be recycled. Decompn. of the catalysts was obsd. when distn. was carried out in the absence of II. .
