The present invention relates to a method for preparing α-hydroxy, α-substituted methylenebisphosphonates and phosphonoacetates via addition of Grignard or organoindium reagents to tetraalkyl carbonylbisphosphonates and trialkyl carbonylphosphonoacetates. Also disclosed are compounds so synthesized.

Processes for removing sulfur and nitrogen contaminants from hydrocarbon streams are described. The processes include contacting the hydrocarbon stream comprising the contaminant with lean halometallate ionic liquid an organohalide resulting in a mixture comprising the hydrocarbon and rich halometallate ionic liquid comprising the contaminant. The mixture is separated to produce a hydrocarbon effluent and a rich halometallate ionic liquid effluent comprising the rich halometallate ionic liquid comprising the contaminant.

An alkylation process utilizing less than 10 vol % of a halometallate based ionic liquid catalyst is described. By decreasing the catalyst volume fraction, the level of subsequent undesirable reactions may be minimized. The total residence time is typically in the range of about 1 min to about 30 min. The alkylate typically has a research octane number of at least about 93, and the olefin conversion is typically at least about 96%.
