quick question re. 1,2-dichloroethane and sodium polysulfide
just because it was cheap, I bought http://www.ebay.co.uk/itm/232180462901?_trksid=p2060353.m274... a 'Chemistry Demonstration Synthetic Rubber' kit for £1,
normally http://www.edulab.com/prod/chemistry-demonstration-synthetic... so probably passed expiry date
so
other than producing uPVC, is there any not too complicated, interesting use for sodium polysulfide or ethylene chloride (I assume 1,2-dichloroethane)
?

Sodium polysulfide with an ammonium salt can probably be used to convert aryl ketones to an isomerized amide-- for example it converts acetophenone to
phenylacetamide. This is the Willgerodt rearrangement: ammonium polysulfide is more common but the combination should work as well. Be sure to safely
destroy the H2S produced!
