Novel syntheses of bis-spiropyran photochromic compounds using ultrasound II

Article abstract of DOI:10.1080/00397919808004964

bis-Spiropyran photochromic compounds derivatives (3', 3'- trimethylindoline-2-spiro-2'-benzopyran), were synthesized using ultrasonic energy (25 kHz, 55 Watts). The reaction times were between 10 to 20 min. and higher yields comparing with the conventional reported methods, were obtained.
