Tosyl isocyanate(Cas 4083-64-1) Usage

Chemical Description	Tosyl isocyanate is an organic compound with the formula CH3C6H4SO2NCO.
Synthesis Reference(s)	Tetrahedron Letters, 35, p. 9609, 1994 DOI: 10.1016/0040-4039(94)88523-0
Hazard	Moderately toxic by ingestion. Low toxicity by inhalation. A mild skin and moderate eye irritant.
Synthesis	Add the organic azide (0.75 mmol), Pd(OAc)2 (5.6 mg, 5 mol%) to an oven-dried Schlenk tube (10 mL). Purge the tube and backfill with CO (three cycles) from a balloon. Inject anhydrous MeCN (3.0 mL) into the tube. Stir at 80°C for 4 h under CO atmosphere (balloon). Concentrate the mixture under reduced pressure. Purify the residue by column chromatography (petroleum ether/EtOAc 3:1.-.1:1).
General Description	p-Toluenesulfonyl isocyanate undergoes palladium-catalyzed bis-allylation reaction with allylstannanes and allyl chlorides.
