Synthesis
Copper halides react with organolithium reagents to form the organocopper compound. Phenylcopper is prepared by reaction of phenyllithium with copper(I) bromide in diethyl ether. Reaction with a second equivalent of R-Li to R-Cu then gives the lithium diorganocopper compound. Copper halides also react with Grignard reagents. The compound pentamesitylpentacopper is prepared from mesityl magnesium bromide and copper(I) chloride. Copper salts add to terminal alkynes to form copper acetylides The copper metallocene (η-cyclopentadienyl triethylphosphine) copper can be prepared by reaction of copper(II) oxide with cyclopentadiene and triethylphosphine in pentane at reflux.

Famous quotes containing the word synthesis:
“It is in this impossibility of attaining to a synthesis of the inner life and the outward that the inferiority of the biographer to the novelist lies. The biographer quite clearly sees Peel, say, seated on his bench while his opponents overwhelm him with perhaps undeserved censure. He sees him motionless, miserable, his head bent on his breast. He asks himself: “What is he thinking?” and he knows nothing.”
—Andre Maurois (1885–1967)
“In order to begin an analysis, there must already be a synthesis present in the mind.”
—Johan Huizinga (1872–1945)
“It is not easy to construct by mere scientific synthesis a foolproof system which will lead our children in a desired direction and avoid an undesirable one. Obviously, good can come only from a continuing interplay between that which we, as students, are gradually learning and that which we believe in, as people.”
—Erik H. Erikson (20th century)
