34 This view is confirmed by Wallach. But as Faust & Homeyer, in 
judging Voelckel’s analyses (these are stated to agree better with 
cymol, C 10 H 14 ) apparently did not consider that Voelckel had 
used P 2 O s in dehydrating cineol, so Hell & Stiircke overlook the 
fact that Faust & Homeyer employed P 2 S 6 . Wallach has shown 
that phosphorus pentasulphide easily converts cynene (dipentene) 
into cymol.
