Tetrahedron Letters | 1973

Base-induced electrocyclic opening of dihydrobenzothiophenes

H. Kloosterziel; J.A.A. van Drunen

Treating 2,3-dihydroxybenzo[b]thiophene with KNH2 gave the s-vinylbenzenethiolate anion. Similarly 1,3-dihydrobenzo[c]thiophene gave the dimethylene-1,3-cyclohexadiene-7-thiolate anion. [on SciFinder (R)]


Journal of The Chemical Society D: Chemical Communications | 1969

Base-induced electrocyclic opening of some heterocyclic compounds

H. Kloosterziel; J. A. A. van Drunen; P. Galama

Dihydrofuran, dihydrothiophen and its 1,1-dioxide, and dihydrobenzoxepin lose a proton and yield open anions upon reaction with KNH2.


Chemical Communications (london) | 1967

Competitive photoisomerizations of 1-substituted cycloheptatrienes

A. P. Ter Borg; E. Razenberg; H. Kloosterziel

Irradn. of 1-substituted cycloheptatrienes gave 2 products as shown in the scheme. The products of irradn. (in %) are tabulated and showed that substituents can change the ratio of competing photochem. pathways by several orders of magnitude. [TABLE OMITTED] [on SciFinder (R)]
