Patent number: 5231190Abstract: Squarylium compounds of the formula: ##STR1## wherein Q.sup.1 and Q.sup.2 are each independently a pyrylium, thiopyrylium, selenopyrylium, benzpyrylium, benzthiopyrylium or benzselenopyrylium nucleus, and R.sup.1 and R.sup.2 are each independently an aliphatic or cycloaliphatic group, can be prepared by reacting a squaric acid derivative of the formula: ##STR2## with a compound of the formula Q.sup.2 CH.sub.2 R.sup.2 in the presence of a base. The derivatives of Formula II may be prepared by condensing a 2,3,4,4-tetrahalocyclobut-2-en-1-one with a compound of the formula Q.sup.1 CH.sub.2 R.sup.1 in the presence of a base to produce a compound of the formula: ##STR3## wherein Q.sup.1 and R.sup.1 are as defined above, and X represents chlorine or bromine, and hydrolyzing the compound of Formula III. Alternatively, the derivatives of Formula II may be prepared by reacting a diester, monoacid chloride monoester or diacid chloride of squaric acid with a compound of the formula Q.sup.1 CH.sub.2 R.sup.Type: GrantFiled: May 6, 1991Date of Patent: July 27, 1993Assignee: Polaroid CorporationInventors: Donald A. McGowan, Paulina P. Garcia, John W. Lee, Thomas K. Spencer, Stephen J. Telfer, Michael J. Zuraw
