33. 6 was allowed to stand for 3 h.
34. When the furan solution of the mixture of 5a and 5b was refluxed for 6 h, almost complete conversion into 5a was observed, indicating that 5a would be thermodynamically more stable than 5b.

36. 2+ by deprotonation has been reported (ref 10b).
37. + (Ir-Ir 2.8727 Å), was obtained. This result suggests that two Ir centers in the intermediate would be kept in close proximity. The details of this reaction will be discussed in due course.
