(Texas A&M University. Libraries, 1986)As PPN⁺ (bistriphenylphosphineimminium) salts the anionic metal hydrides HFeM(CO)₉⁻ (M = Cr, Mo, W) were shown to be olefin isomerization catalysts under mild conditions (25°C, fluorescent lighting) toward the conversion ...
-
(Texas A&M University. Libraries, 1986)In the past five years, the search for alternative sources of petrochemical feedstocks has turned attention toward non-conventional sources of chemical carbon other than carbon monoxide. A renewed interest in the chemistry ...

(Texas A&M University. Libraries, 1986)The cis-M(CO)4 (13CO)PR3 [double harpoon] trans-M(CO)4(13CO)PR3 CM = Cr, R = Et; M = W, R = OMe, Me, Et, i-Pr) isomerization reactions have been studied kinetically in cyclohexane-d12 by 13C NMR spectroscopy. These ...
-
(Texas A&M University. Libraries, 1992)The Gif-family is a group of Fe- or Cu-containing chemical systems oxidizing saturated hydrocarbons to ketones. The unusual behavior shown by these systems (secondary C-H bonds are oxidized preferentially even in the ...
-
(Texas A&M University. Libraries, 1988)The intermetallic compounds of the Brewer-Engel type represent a unique case in novel heterogeneous catalyst systems. The components of these alloys are known to have altered electronic structures described as sharing of ...
-
(Texas A&M University. Libraries, 1986)Ethylene oligomers having diphenylphosphine, diaryl and triaryl phosphite functional groups were used as supports for hydrogenation, hydroformylation and diene cyclooligomerization catalysts. An advantage of these ethylene ...
-
(Texas A&M University. Libraries, 1987)The group 6 anionic transition metal hydrides, HM(CO)4L- (M = Cr, W; L = CO, P(OMe)3 were found to be convenient reagents in organic and organometallic synthesis. These reagents offer the advantages of high selectivity, ...

(2012-10-19)The use of polymer supports for transition metal catalysts are very important and useful in synthetic organic chemistry as they make possible the separation and isolation of catalysts and products quite easy. These ...
