Hydrocarbon-Soluble Bis(trimethylsilylmethyl)calcium and Calcium-Iodine Exchange Reactions at sp2-Hybrized Carbon Atoms

Hydrocarbon-soluble and highly reactive [(L)xCa(CH2SiMe3)2] (L = tetrahydropyran, x = 4 (2a); L = tmeda, x = 2 (2b)) is synthesized by the metathesis reaction of Me3SiCH2CaI (1-I) with KCH2SiMe3. The durability of 2a in tetrahydropyran solution at 0 °C is sufficiently high for subsequent chemical transformations. The reaction of ICH2SiMe3 with calcium in diethyl ether yields unique cage compound [(Et2O)2Ca(I)2·(Et2O)2Ca(I)(OEt)·(Et2O)Ca(I)(CH2SiMe3)] (3). We demonstrate that alkylcalcium complexes are valuable reagents for calcium-iodine exchange reactions at Csp2-I functionalities.

1-CHLOR-1-PHOSPHIRANE

The title compounds are prepared by reaction of disubstituted diazomethanes with 1-chloro-2-phenyl-2-trimethylsilyl-1-phosphaalkene.The chemistry of the 1-chloro-1-phosphiranes is described.

Synthesis and Chemical Behaviour of Thioacylsilanes (Silyl Thioketones). Part 1. Oxidation to S-Oxides, Conversion into Silylated Thiiranes, Silylated Triarylethylenes, and α-Silylated Sulphides

Trimethylsilyl and triphenylsilylaryl thioketones have been synthesized by acid catalysed reaction of the corresponding ketones with hydrogen sulphide.Such silylated thioketones heve been oxidized to give S-oxides and converted with diaryldiazomethanes into triaryl thiiranes; upon treatment with organolithium nucleophiles they undergo thiophilic addition.The ready desulphurization with triphenylphosphine of silylated thiirans to the corresponding silyl triaryl ethylenes is also reported.

SILYLATED THIIRAN-1-OXIDES: STRUCTURE, RING OPENING AND CONVERSION TO A BENZOTHIOPHENE.

Silylated thiirans upon oxidation with peroxyacids do not give exclusively the corresponding S-oxides but, in addition, some products derived from ring opening.The stereochemistry of the oxidation to thiiran-1-oxides is anti to the silyl group as demonstr

Silyl Thioketones and Silylated Thiirans

The preparation of silyl thioketones, and their reactions leading to silylated thiirans and other hitherto unknown silylated heterocycles, are reported.
