Propanedioic add

Dimethyl mesoxolate Propanedioic acid, oxo-, dimethyl ester (9) (3298-40-6) Dimethyl benzalmalonate Malonic add, benzylidene-, dimethyl ester (8) Propanedioic add, (phenylmethylene)-, dimethyl ester (9) (6626-84-2) Dimethyl sulfide Methyl suflide (8) Methane, thiobis- (9) (75-18-3)... 

Under photoirradiation conditions 2-(phenylseleno)propanedioates add to a variety of olefins and acetylenes regioselectively in good yields via phenylseleno group transfer [121]. The group transfer addition of methyl(phenylseleno)malononitrile to a variety of alkenes has been investigated in detail as depicted in Scheme 15.46 group transfer addition to phenyl 1-propenyl sulfide proceeds with high anti selectivity [122]. 

Dimethyl diazomaionate Malonic acid, diazo-, dimethyl ester (8) Propanedioic add. diazo-, dimethyl ester (9) (6773-29-1)... 

Add 30 cm concentrated sulphuric acid slowly to 399 cm cooled water and dissolve in the solution 10 g propanedioic acid, 3.9 g potassium bromate and 0.4 g ammonium hexanitrocerate(IV). Add to the solution drops of 0.025 M ferroin indicator (>14 cm ) to give a visible colour. Stir magnetically and note the change in colour from blue to red. Alternatively, insert a platinum electrode into the solution and dip a calomel electrode through a salt bridge in the solution. Connect the two electrodes to a mV meter and...
