the corresponding tricyclohexylphosphine complex (pcy3)2cl2ru=chch=cph2 shown active. work culminated in commercially available 1st generation grubbs catalyst in 1995. second generation catalysts have been developed well.
ruthenium stable in air , has higher selectivity , lower reactivity molybdenum, promising of discovered catalysts. in addition, grubbs took green chemistry approach catalysis reduced potential create hazardous waste. grubbs catalyst has become standard general metathesis applications in ordinary laboratories.
by controlling catalyst used, becomes possible synthesize polymers specialized structures , functional capabilities, including cyclic olefins, alternating copolymers, , multiblock copolymers. using catalysts allows chemists speed chemical transformations , lower cost of complicated multi-step industrial processes.
commercial activities
both first , second generation grubbs catalysts commercially available materia, startup company grubbs co-founded mike giardello in pasadena, california in 1998. materia has been able obtain exclusive rights manufacture many of known olefin catalysts. under giardello, materia able sell catalysts through sigma-aldrich s chemicals catalogue. sigma-aldrich became exclusive worldwide provider. in 2008, materia partnered cargill form elevance renewable sciences produce specialty chemicals renewable oils, including biofuels.
grubbs member of reliance innovation council formed reliance industries limited, india.
grubbs member of usa science , engineering festival s advisory board.
awards , honors
grubbs received 2005 nobel prize in chemistry, along richard r. schrock , yves chauvin, work in field of olefin metathesis. has received number of other awards , honors well, including following:
