A new and very convenient one-carbon ringcontractionmethod is reported. Pyrolysis of α-substituted cycloalkanones at 600–650 °C under flow conditions produces the ring contracted compounds under loss of carbon monoxide. Substrates varying in ring size and nature of the α-substituent have been investigated.
The present invention relates to composition comprising at least one compound obtained from the reaction of at least one compound (i) having a refractive index n
D
20
of at least 1.50 comprising at least one isocyanate-reactable functional group-XH, wherein each of X is, independently, O or NR, at least one polyisocyanate (ii), and, optionally, at least one compound (iii) comprising at least one isocyanate-reactable functional group —YH and at least one curable functional group Q, wherein each of Y is, independently, O, NR or S, and its use for making high refractive index coatings and films.
Disclosed is a compound represented by formula (1) or a pharmacologically acceptable salt thereof. (In the formula, R
1
is optionally substituted heteroaryl etc.; R
2
is hydrogen etc.; R
3
and R
4
are each independently hydrogen etc., R
5
is the following group: (wherein Y is optionally substituted five membered heteroaryl etc., R
9a
is optionally substituted aryl etc., R
9b
and R
9c
are each dependently hydrogen etc., and m is the integral 0 etc.) etc.; R
6
is hydrogen etc.; and R
7
is hydrogen etc.
