PMR, UV, and IR spectroscopy was used to study the structure of the reaction of 1-hydroxy-3,3-dialkyl-1-arylphthalanes (Alk= CH3, C2H5, and iso-C3H7), their methyl ethers and thiosemicarbazide salts.The compounds containing Ar = C6H5, o-CH3C6H4, m-CH3C6H4, o-CH3OC6H4, m-CH3OC6H4, p-CH3OC6H4, p-C2H5OC6H4, p-(CH3)2NC6H4, p-ClC6H4, m-FC6H4, and 3,4-(CH3O)2C6H3 have cyclic 1-thiosemicarbazido-3,3-dialkyl-1-arylphthalane structure, while the compound with Ar= 2,4,6-(CH3)3C6H2 has the structure of the thiosemicarbazone of the isomeric o-aroylbenzyl alcohol.The cyclic products of the rea ction with Ar = o-CH3C6H4 in ethanol undergo opening of the heterocycle to form open-chain isomers.
