- Abstract
- The unequivocal solid-state structure and stereochemistry of the hetaryl leuco-TAM dye, 2,2'-(2-phenyl propane- 1,3-diylidene) bis(1, 3,3-trimethylindoline) derivatives were established using X-ray single crystal analysis The X-ray crystal analysis showed that the (Z, E)-isomers only formed stereoselectively. with a so-called "three-bladed propeller" conformation, from the reaction of a Fischer base and benzaldehyde derivatives These isomers were stacked in a juxtaposition to form a dimer ora double dimer, adopting either a triclmic, with P-1, or monoclinic crystal system with a space group P2 l/n m the unit Cell Of the crystal
