Title: Deoxygenation of cis vicinal diols
Inventor: CLIVE DERRICK LAWRENCE JOEL
IPC: C07H19/06
Filed: 1994-02-01
Abstract: Cis vicinal diols are converted to olefins using tellurides or selenide reagents. The diol is reacted to convert the hydroxyl groups into good leaving groups for nucleophilic substitution. Alkyl and aryl sulfonate groups such as mesylate or tosylate are preferred. The product is then reacted with a source of Tc2- or Se2- ions, preferably an alkali metal telluride or selenide, to form the desired olefin. The process is particularly useful for generating 2',3'- unsaturation in the sugar moiety of nucleosides. Novel intermediate mesylate, tosylate and olefin derivatives of nucleosides are also provided.

Title: Method of operating a gas-turbine group
Inventor: KAMBER PETER
IPC: F02C9/28
Filed: 1995-10-12
Abstract: In a method of operating a gas-turbine group having sequential combustion, action is taken first of all  on  the  inlet  temperatures  (A,  B)  at  the  two turbines  (6,  10)  in order to provide a partial-load operation.  The subsequent lowering of the load takes place by adjustment of the compressor guide blades (C), that is, by reducing the mass flow (E) to below 50% of the rated load  (X).  During this  lowering,  the inlet temperature  (A)  at  the  first  turbine  (6)  is  kept constant, while the other inlet temperature (B) at the second turbine (10) is continuously lowered; the outlet temperature  (D)  of  the  second  turbine  (10)  is  in contrast kept constant. After the lowering of the load is complete by adjusting the compressor guide blades, the inlet temperatures (A, B) are reduced directly or in a phase-displaced manner (Y).
