There is disclosed a method for producing an alkoxytitanium complex of formula ( I ),
wherein Cp is a group having cyclopentadiene-type anion skeleton, A represents a carbon atom or silicon atom, R1, R2, R3, R4, R5 and R6 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms which optionally may be substituted and the like, and R7 each independently represents an alkyl group having 1 to 10 carbon atoms which may be substituted and the like.

Abstract : Trans-Diphenyl-1,2-dioxetane was prepared by cyclization of the corresponding beta-bromohydroperoxide. Thermaldecomposition of this compound proceeds with an activation energy of 23 + or - 1.6 kcal/mol to yield benzaldehyde 10 + or - 2% of which was in an excited triplet state. The effects of replacement of a dioxetane ring proton with a deuterium were investigated. No detectable partitioning
