In this paper, an algorithm for mapping positive polarity Reed-Muller (PPRM) coefficients from canonical sum of products (CSOP) coefficients is presented. Another algorithm for mapping CSOP coefficients is also presented. Both algorithms are more space efficient than the existing algorithms.

A wide variety of carbonyl compounds 1 can be easily protected selectively as the corresponding 1,3-oxathiolanes 2 in good yields using a catalytic amount (0.01-0.1 equiv.) of n-tetrabutylammonium tribromide in dry CH 2 Cl 2 at 0-5 Β°C. On the other hand, various 1,3-oxathiolanes 2 can be deprotected

The facile one-pot reaction of the stable N-heterocyclic silylene LSi: 1 (L=(ArN)C(=CH(2))CH=C(Me)(NAr), Ar=2,6-iPr(2)C(6)H(3)) with Me(2)Zn, Me(3)Al, H(3)Al-NMe(3), and MeLi has been investigated. The silicon(II) atom in 1 is capable of insertion into the corresponding M-C and Al-H bonds under very
