The following entries in Table I were interchanged: for compound 10, C-9 and C-14; for 21, C-1 and C-17; for 29, ‘2-14 and C-17. In Table I1 for 6P-AcO-Androstane, C-3 and C-4 should be reversed. Table 111: for 5ct entry “0.0 (19) t’’ should be 3.9 (19) t; for 12P entry “1.2 (9) t” should be -1.2 (9) t. K. T. Potts* and J. L. Marshall: Thiazolo[3,4-b]indazole, a Ring-Fused Tetravalent Sulfur Thiazole System. Page 129. In structure 3, the group, SC(Ph)=NHZ-, shown in the upper left is in error and should be replaced by R (as shown in structure 4).

In the title as well as in the last line of the right column of page 145 and the fifth line of the left column of .page 146, the correct ending for the name is benzothiolidene.

The third word should be starting. Page 926, Table VII. The upper part of this table should have a subheading reading as follows: Cyclohexene, 0.1 mg of Rh.

The structure assigned to compound 9 is incorrect. A structure in better accord with the available evidence is that shown below. The authors acknowledge Dr. R. S. Atkinson for first suggesting the discrepancy.

Page 2876. Because the structure of 9 was incorrect, Scheme I is also incorrect.

Lines 24 and 25 should read as follows. increased for the products from the other isomer. However, the value of K which accounts for the observed 82% retention found for the first experiment in Table I1 leads to a prediction of 69% retention for the second experiment in the table. Conversely, a value of K which accommodates the observed 120% retention in the second experiment leads to a prediction of 50% retention for the first experiment in the table. Accordingly, the predicted extent of. Page 3056, column 2, line 49. “100%”should be replaced by 67%.

Bargar” should be Thomas M. Bargar. Page 3154. Reference 12a should have cited H. Nieuwenhuyse and R. Louw, J. Chern. Soc., Perkin Trans. 1,839 (1973), which reverses these authors’ previous assignment of configurations for 1,2-bis(methylsulfiny1)ethane (1);accordingly, they find that the 01 form is actually the meso diastereoisomer.

It is regretted that, at the time of writing the paper, the authors were unaware of Dr. LeCorre’s work [Bull.SOC.Chirn. Fr., Nos. 9-10, 2005 (1974); C. R. Acad. Sci. Paris, 963 (1973)] showing that vinyl ethers are formed when the two stabilized phosphoranes, benzylidene and ethoxycarbonylmethylene, react with formate esters.
