Yttrium chloride catalyzed reaction of arylglyoxal and alcohol resulted in highly selective formation of α-aryl-α-hydroxyacetic ester under the influence of an added base (triethylamine, pyridine, piperidine) and afforded acetal in the absence of the base. The possible role of the additive (base) is discussed.

Liquid highly active photoinitiators are obtained by dissolving a solid photoinitiator of the titanocene type in liquid photoinitiators of the acetal or ketal type. The liquid mixtures have a long dark storage stability.
Oxygen-containing titanocenes, and the use thereof
-
, (2008/06/13)
Titanocenes of the formula I STR1 in which R1 are cyclopentadienyl? groups and R2 and R3 are aromatic radicals which are substituted in both ortho-positions by fluorine and, in addition, are substituted by an acyloxy group are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds.
Titanocenes, the use thereof, and N-substituted pyrroles
-
, (2008/06/13)
Titanocenes containing two 5-membered cyclodienyl groups, for example cyclopentadienyl, and one or two 6-membered carbocyclic or 5- or 6-membered heterocyclic aromatic rings which are substituted by a fluorine atom in at least one of the two ortho-positions to the titanium-carbon bond and contain, as a further substituent, unsubstituted or substituted 1-pyrryl, are suitable as photoinitiators for radiation-induced polymerization of ethylenically unsaturated compounds.
Titanocenes, the use thereof, and n-substituted fluoroanilines
-
, (2008/06/13)
Titanocenes containing two 5-membered cyclodienyl gropus, for example cyclopentadienyl, and one or two 6-membered carbocyclic or 5- or 6-membered heterocyclic aromatic rings which are substituted by a fluorine atom in at least one of the two ortho-positions to the titanium-carbon bond and contain, as further substituents, a substituted amino radical, are suitable as photoinitiators for radiation-induced polymerization of ethylenically unsaturated compounds.
Novel nitrogen-containing titanocenes, and the use thereof
-
, (2008/06/13)
Titanocenes of the formula I STR1 in which R1 are cyclopentadienyl? groups and R2 and R3 are aromatic radicals which are substituted in both ortho-positions by fluorine and, in addition, are substituted by a pyrrylalkyl group, amidoalkyl group or imidoalkyl group, are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds.
