The photocycloaddn. of 1-naphthonitrile (1-NpCN) and 2,3-dimethyl-2-butene in cyclohexane or benzene gave cyclobutane I primarily, but that of 2-NpCN gave azetine II as the major and cyclobutane III as the minor product in low conversion photolysis. The photocycloaddn. of 1-NpCN with DMB is retarded by increasing amts. of trifluoroacetic acid which is shown to form non-photoreactive complexes with ground state as well as with singlet excited state 1-NpCN. It also quenches the *(1-NpCN-DMB) exciplex.

The results showed that the reaction activity between glycinin (7S subunit) and maltodextrin was high, and the reaction proceeds quantitatively regardless of the variation of protein and polysaccharide mass ratio. The molecular properties of the formed conjugates are also highly uniform. The reaction activity between β-conglycinin (11S subunit) and maltodextrin is relatively lower Compared to that of glycinin, and the molecular properties of these conjugates are affected by the variation of the R values.
