    Abstract: A compound comprising a class of sulfonated triorganophosphine compounds of formula R 1 R 2 P-R 3 [-O-(CH 2 ) n -(SO 3 M)] m , wherein the R 1 and R 2 are selected individually from alkyl, aralkyl, and alicyclic groups, wherein R 3 represents a divalent or polyvalent alkylene or alicyclic radical that is bonded to the phosphorus atom and to one or more sulfonate substituents via an alkylether link, and further wherein R 3 does not contain any aryl moieties; n is an integer reflecting a number of methylene groups in the alkylether link; M represents a monovalent cation; and m is an integer representing a total number of sulfonated alkylether substituents. The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alky-aryl exchange, thereby leading to reduced ligand usage and improving ligand and rhodium recovery and recycling.

    Abstract: Phosphines having two aryl groups and one alkyl-substituted cycloalkyl group bonded to a phosphorus atom are formed by reacting an alkali metal diarylphosphide with a monoalkyl- or polyalkyl-substituted cycloalkyl mesylate or tosylate in which an alkyl group is in the 2-position, in a liquid reaction medium in which these reactants are soluble. This process avoids complications associated with prior known process technology for producing such phosphines. The phosphines are useful as ligands for making noble metal catalysts.

    Abstract: A process for making a cycloalkyl phosphine comprising hydrogenating an aryl phosphine in the presence of an effective amount of an aryloxide of a metal selected from the group consisting of niobium and tantalum is disclosed. Cycloalkyl phosphine products of this process, useful as ligands in a complex of a transition metal which acts as a catalyst in the formation of stereoisomers, are also set forth. Furthermore, niobium or tantalum organometallic compounds, generated in this process, useful in the catalytic hydrogenation of aryl phosphines and arene-containing polymers, is also described.
