Cyclobutanedicarboxylic acids

DIETHYL 1,1-CYCLOBUTANEDICARBOXYLATE (1,1-Cyclobutanedicarboxylic acid, diethyl ester)... [Pg.72]

If this extraction with ether is omitted the yield of 1,1-cyclobutanedicarboxylic acid is 3-4 g. less. [Pg.73]

Cyclobutanedicarboxylic acid has been prepared by hydrolysis of the ethyl ester,1 or of the half nitrile, 1-cyano-l-car-boxycyclobutane.2 The ethyl ester has been prepared by condensation of ethyl malonate with trimethylene bromide1 or chloro-bromide.3 The half nitrile has been prepared by condensation of trimethylene bromide with ethyl cyanoacetate followed by hydrolysis of the ester to the acid.2... [Pg.73]

Sulfonium, cyclopropyldiphenyl tetrafluoroborate, 54, 28 Sulfonium salts, acetylenic, furans from, 53, 3 Sulfonium ylides, 54, 32 Sulfur, reaction with organo-lithium compounds, 50, 105 Sulfuryl chloride, with 1,1-cyclobutanedicarboxylic acid to give 3-chloro-l,1-cyclobutanedicarboxylic acid, 51, 73... [Pg.65]

CHLORO-,51, 73 1,1-Cyclobutanedicarboxylic acid, with sulfuryl chloride to give 3-chloro-1,1-cyclobutanedicarboxylic acid, 51,73... [Pg.73]

Many platinum analogs, and analogs based on other metal centres, have been prepared and evaluated. Carboplatin (7.89, cA-diammine(l,l cyclobutanedicarboxalato)platinum) has markedly reduced gastrointestinal and renal toxicity in comparison with cisplatin. It is prepared by the treatment of cA-Pt(NH3)2l2 with silver sulphate, followed by the barium salt of 1,1-cyclobutanedicarboxylic acid. [Pg.454]
