Diazomethane → HCID 53649795, compound

Participants

Reaction Steps

To a stirred solution of diazomethane (9.66g, 0.23 mole) in dry ether (1250 ml.) maintained at 0° to -5°, was added a suspension of the styrene-carbonyl chloride polymer (10.0g) from example 7(c) in methylene chloride (50 ml.) over 15 minutes. Stirring was maintained for 5 hours at 0° to -5° and then for 16 hours at room temperature. The reaction mixture was filtered and the polymer washed with ether (2 × 100 ml.) and chloroform (2 × 100 ml.) and dried in vacuo at room temperature to constant weight. The title polymer (10.76g) was deep yellow in colour and the IR spectrum exhibited absorptions at 2100 (diazo) and 1610 (carbonyl) cm-1. The composition of the polymer was confirmed by microanalysis.
