Patent ID: 7179932

Claim:
A compound comprising a cis-diol having the formula: wherein: R 1 , R 2 , and R 3 are each independently selected from hydrogen, a halogen, aryl, a linear or branched C 1 –C 18 alkyl, a linear or branched C 2 –C 18 alkenyl, a linear or branched C 2 –C 18 alkynyl, halomethyl, OR, SR, NR 2-3 , or O(CO)R; R 4 is selected from hydrogen, a halogen, linear or branched C 1 –C 18 alkyl, linear or branched C 2 –C 18 alkenyl, linear or branched C 2 –C 18 alkynyl, halomethyl, CF 3 , CN, NO 2 , SR, OR, NR 2-3 , O(CO)R, SiR 1 R 2 R 3 , or a bridging group between two arene or substituted arene moieties; n is 0–3; R is hydrogen, linear or branched C 1 –C 18 alkyl, or SiR 1 R 2 R 3 ; X is a divalent linear or branched C 1 –C 18 alkyl, C 2 –C 18 alkenyl, or C 2 –C 18 alkynyl spacer, except when X=C 2 alkynyl and R 1 =R 2 =R 3 then R 1 =R 2 =R 3 cannot be —CH 3 .
