There are disclosed masked Lewis acids into compounds in which the Lewis acid can be released by exposure of the compound to light, especially ultraviolet light. These compounds can be represented by the following formula (I): ([(AEX(3-n))(n+1)Yn](n+1)-)m(Qm+)(n+1) (I). wherein briefly, E represents boron or aluminium, X is an aryl group and Y is -Ar'EAX,. These compounds are used as catalyst for hydrosilylation reaction, crosslinking of polymers, or ester deprotection reactions as photo Lewis acid generator (PhLAG).

A molecule that releases the strong organometallic LewisacidB(C(6)F(5))(3) upon irradiation with 254 nm light has been developed. This photo Lewisacid generator (PhLAG) now enables the photocontrolled initiation of several reactions catalyzed by this important Lewisacid. Herein is described the synthesis of the triphenylsulfonium salt of a carbamato borate based on a carbazole function, its establishment
