Two types of allylic carbon–carbon bond cleavage are summarized in this chapter. One is retro‐allylation of homoallylic alcohols, the reverse transformation of carbonyl allylation. Catalytic retro‐allylation has been emerging as a useful tool in organic synthesis because (i) it provides an unusual transformation from homoallylic alcohol to the corresponding ketone and allylic moiety, (ii) it represents...
Triisopropylsilyltetrathiafulvalene (TIPS‐TTF) has been devised as a promising platform for the synthesis of low‐symmetry TTF derivatives. The bulky TIPS group allows TIPS‐TTF to undergo palladium‐catalyzed direct diarylation as well as LDA‐mediated dilithiation exclusively on the roomier dithiole ring. Subsequent fluoride‐mediated protodesilylation provided vicinally difunctionalized TTF, which could...
