A polymerizable liquid crystal compound is represented by the following formula (1):
P-Sp
1
-L
1
-M
1
-L
2
-Sp
2
-Ox (1)
wherein P represents a polymerizable group; one of Sp
1
and Sp
2
represents a branched alkylene group, or an alkylene group containing, in the chain thereof, at least one divalent linking group selected from the group consisting of —O—, —C≡C— and —S—; the other of Sp
1
and Sp
2
represents a straight chain alkylene group; each of L
1
and L
2
independently represents a divalent linking group; M
1
represents a mesogenic group; and Ox represents a substituent containing an oxetanyl group.

functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zincalkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives
