efficiently from cycloisomerization of but-2-yne-1,4-diols with or without 1,3-dicarbonyl compounds is described. By taking advantage of the orthogonal modes of reactivity of the alcoholic substrate through slight modification of the reaction conditions, a divergence in product selectivity was observed. At roomtemperature, p-TsOH·H2O-mediated tandem alkylation/cycloisomerization of the propargylic
The present invention relates to photochromic materials that include a photochromic compound that includes a photochromic substituent (e.g., an indeno-fused naphthopyran) and at least one pendent silane group, which is bonded to the photochromic substituent. The pendent silane groups are selected from certain pendent siloxy-silane groups and/or pendent alkoxy-silane groups represented by general formulas (I) and/or (II) as described in further detail herein. The present invention also relates to photochromic articles, such as photochromic optical elements (e.g., photochromic lenses), and photochromic coating compositions (e.g., curable photochromic coating compositions), that include the photochromic materials of the present invention. The photochromic materials of the present invention have improved compatibility with compositions into which they may be incorporated, for example, coating compositions, such as urethane coating compositions.
